Hydrostatic pressure, cartilage, synovial membrane, infrapatellar fat pad, transforming growth factor (TGF)-β3, stem cells, chondrocytes

Abstract: Hydrostatic pressure (HP) is a key component of the in vivo joint environment and has been shown to enhance chondrogenesis of stem cells. The objective of this study was to investigate the interaction between HP and TGF-β3 on both the initiation and maintenance of a chondrogenic phenotype for joint tissue derived stem cells. Pellets generated from porcine chondrocytes (CCs), synovial membrane derived stem cells (SDSCs) and infrapatellar fat pad derived stem cells (FPSCs) were subjected to 10 MPa of cyclic HP (4 h/day) and different concentrations of TGF-β3 (0, 1 and 10 ng/mL) for 14 days. CCs and stem cells were observed to respond differentially to both HP and TGF-β3 stimulation. HP in the absence of TGF-β3 did not induce robust chondrogenic differentiation of stem cells. At low concentrations of TGF-β3 (1 ng/mL), HP acted to enhance chondrogenesis of both SDSCs and FPSCs, as evident by a 3-fold increase in Sox9 expression and a significant increase in glycosaminoglycan accumulation. In contrast, HP had no effect on cartilage-specific matrix synthesis at higher concentrations of TGF-β3 (10 ng/mL). Critically, HP appears to play a key role in the maintenance of a chondrogenic phenotype, as evident by a down-regulation of the hypertrophic markers type X collagen and Indian hedgehog in SDSCs irrespective of the cytokine concentration. In the context of stem cell based therapies for cartilage repair, this study demonstrates the importance of considering how joint specific environmental factors interact to regulate not only the initiation of chondrogenesis, but also the development of a stable hyaline-like repair tissue…read more

The Influence of Construct Scale on the Composition and Functional Properties of Cartilaginous Tissues Engineered Using Bone Marrow-Derived Mesenchymal Stem Cells by Dr. Meyer

Comments Off

Dr. Meyer has recently published a research paper in Tissue Engineering:

Abstract

Engineering cartilaginous tissue of a scale necessary to treat defects observed clinically is a well-documented challenge in the field of cartilage tissue engineering. The objective of this study was to determine how the composition and mechanical properties of cartilaginous tissues that are engineered by using bone marrow-derived mesenchymal stem cells (MSCs) depend on the scale of the construct. Porcine bone marrow-derived MSCs were encapsulated in agarose hydrogels, and constructs of different cylindrical geometries (Ø4×1.5 mm; Ø5×3 mm; Ø6×4.5 mm; Ø8×4.5 mm) were fabricated and maintained in a chemically defined serum-free medium supplemented with transforming growth factor-β3 for 42 days. Total sulfated glycosaminoglycan (sGAG) accumulation by day 42 increased from 0.14% w/w to 0.88% w/w as the construct geometry increased from Ø4×1.5 to Ø8×4.5 mm, with collagen accumulation increasing from 0.31% w/w to 1.62% w/w. This led to an increase in the dynamic modulus from 90.81 to 327.51 kPa as the engineered tissue increased in scale from Ø4×1.5 to Ø8×4.5 mm. By decreasing the external oxygen tension from 20% to 5%, it was possible to achieve these higher levels of mechanical functionality in the smaller engineered tissues. Constructs were then sectioned into smaller subregions to quantify the spatial accumulation of extracellular matrix components, and a model of oxygen diffusion and consumption was used to predict spatial gradients in oxygen concentration throughout the construct. sGAG accumulation was always highest in regions where oxygen concentration was predicted to be lowest. In addition, as the size of the engineered construct increased, different regions of the construct

preferentially supported either sGAG or collagen accumulation, thus suggesting that gradients in regulatory factors other than oxygen were playing a role in determining levels of collagen synthesis. The identification of such factors and the means to control their spatial concentration within developing tissues represents a central challenge in engineering large cartilaginous grafts.

Sports Injury Prevention Using Subject-Specific Models by Dr. Eric G. Meyer

Comments Off

If you are part of the recent Blue Devil varsity sports revival, if you played sports competitively in high school, or even if you enjoy a weekend game with a couple of friends or family members, there are pretty good chances that you’ve experienced something in common. In young adults (18-44 years old) musculoskeletal injuries are reported by 38% of the population per year. Sports-related injuries represent 10-19% of all the injuries treated in emergency rooms. Injuries to the ankle and knee, in specific, are the most frequent injuries in sports.

100,000 athletes/year in the US. A classic sign of an ACL tear is hearing a “pop” that occurs while landing, cutting or pivoting. Although most do not involve contact with another player, it is very difficult to determine the exact cause of these injuries. Similarly, ankle sprains account for 10-30% of sports injuries, but the proposed mechanism for a severe injury, the “high ankle sprain” could not (until very recently) be reproduced in the laboratory. Ligament sprains often occur due to excessive torque in the knee and ankle. Linear traction is necessary for athletic performance, but excessive rotational traction between the shoe and surface is a factor for these injuries. Because of the complex interaction between risk factors, body positioning and external loading, biomechanical research into injury mechanisms must involve multiple investigative strategies (Figure 1).

For the investigation of high ankle sprains due to rotational traction, our research has included cadaver, surrogate, in vivo and in silico (computer simulation) approaches. The most recent step was the development of a three-dimensional computer

model of the anklethat can predict the amount of deformation (strain) occurring in each ligament (Figure 2) during a particular sports scenario. The ligaments undergoing the most strain vary for different ankle positions and loading mechanisms and may represent the structure most at risk for injury. This model was validated based on cadaver experiments and then used with video analysis to accurately predict the ankle injuries. A limitation of this study is that a generic ankle joint model was used to simulate each of these scenarios. There is tremendous natural anatomical variation, such as size differences between males and females, and geometric differences between people with high aches or flat feet. Therefore, the most cutting-edge research today is moving towards using subject-specific models that are based on CT & MRI images from each ankle joint.

Figure 2

Technology and computer software for processing medical images and running computer simulations have advanced tremendously in recent years. Lawrence Tech undergraduates will have the opportunity to experience this innovation in the newly updated Biomedical Engineering Computer Graphics Laboratory (BME 1201) starting in the 2012 spring semester. This course will utilize the MimicsSE software by Materialise (a company with its US headquarters in Plymouth, MI and employer to this issue’s Alumni Spotlight, Danielle Beski) to teach medical images processing and creation of 3D models.

The risk of knee and ankle sprains during sports is a very complex problem. But as our understanding of each risk factor and injury mechanism increases through multidisciplinary research, engineers can create new solutions and safer designs so that young and aging athletes can avoid injury and increase their enjoyment of sports.

 

Footwear Properties and Football Injuries

Comments Off

FootwareExcessive rotational traction that occurs at the interface between the shoe and the playing surface, as well as shoe properties such as rotational stiffness, may have the potential to influence the high incidence of lower extremity injuries in athletes.

By Feng Wei, PhD, and Eric G. Meyer, PhD

American football is one of the most popular sports in the United States. In 2010 more than 1.1 million male high school athletes from more than 14,000 high schools and more than 66,000 male collegiate athletes played football. Participation in high school football has been continuously increasing, with more than 100,000 additional participants (a 12.2% increase) between 1997 and 2007. Football is also a leading cause of sports-related injuries. Out of all high school sports, football has the highest overall injury rate, almost twice that of basketball. Reports estimate that more than 300,000 high school athletes sustain football-related injuries annually…read more. Dr. Meyer

International Research Council on the Biomechanics of Impact Conference

Comments Off

Dr. Meyer recently presented his research at the International Research Council on the Biomechanics of Impact Conference in Dublin, Ireland.

Abstract: High ankle sprains represent a severe injury in sports. External foot rotation is suspected in these cases, but the mechanism of injury remains unclear. The objective of the current study was to integrate in vitro and in vivo experiments along with computational models based on rigid bone surfaces and deformable ligaments of the ankle to investigate the external foot rotation injury mechanism with different shoe constraints and ankle positioning. Injuries and the highest strains occurred in the anterior deltoid ligament (ADL) when the foot was held in neutral with athletic tape. Similarly, ADL strains were highest when a football shoe design with a high rotational stiffness was used to constrain the foot. For a flexible shoe, the anterior tibiofibular ligament (ATiFL) strain was increased and ATiFL injury occurred due to increased talar eversion. In human subjects performing a similar movement, the highest strains also occurred in the ATiFL and ADL. The models showed that ATiFL strain was positively correlated with ankle eversion, but eversion decreased strain in the ADL. Finally, the consequence of eversion on ATiFL strain was confirmed in the first cadaver study that consistently generated high ankle sprains in the laboratory.

Eversion during external rotation of the human cadaver foot produces high ankle sprains

Comments Off

Dr. Meyer’s paper published in September’s issue of the Journal of Orthopaedic Research

Abstract:
While high ankle sprains are often clinically ascribed to excessive external foot rotation, no experimental study documents isolated anterior tibiofibular ligament (ATiFL) injury under this loading. We hypothesized that external rotation of a highly everted foot would generate ATiFL injury, in contrast to deltoid ligament injury from external rotation of a neutral foot. Twelve (six pairs) male cadaveric lower extremity limbs underwent external foot rotation until gross failure. All limbs were positioned in 20° of dorsiflexion and restrained with elastic athletic tape. Right limbs were in neutral while left limbs were everted 20°. Talus motion relative to the tibia was measured using motion capture. Rotation at failure for everted limbs (46.8 ± 6.1°) was significantly greater than for neutral limbs (37.7 ± 5.4°). Everted limbs showed ATiFL injury only, while neutral limbs mostly demonstrated deltoid ligament failure. This is the first biomechanical study to produce isolated ATiFL injury under external foot rotation. Eversion of the axially loaded foot predisposes the ATiFL to injury, forming a basis for high ankle sprain. The study helps clarify a mechanism of high ankle sprain and may heighten clinical awareness of isolated ATiFL injury in cases of foot eversion prior to external rotation. It may also provide guidance to investigate the effect of prophylactic measures for this injury. © 2012 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.
