Osmolarity modulates the de-differentiation of horse articular chondrocytes during cell expansion in vitro: implications for tissue engineering in cartilage repair.

Abstract: Due to the importance of joint disease and ostearthritis (OA) in equine athletes, new regenerative treatments to improve articular cartilage repair after damage are gaining relevance. Chondrocyte de-differentiation, an important pathogenetic mechanism in OA, is a limiting factor when differentiated articular chondrocytes are used for cell-based therapies. Current research focuses on the prevention of this de-differentiation and/or on the re-differentiation of chondrocytes by employing different strategies in vitro and in vivo. Articular chondrocytes normally live in a condition of higher osmolarity (350-450 mOsm/L) compared to normal physiological fluids (~ 300 mOsm/L) and some studies have demonstrated that osmolarity has a chondroprotective effect in vitro and in vivo. Therefore, the response of horse articular chondrocytes to osmolarity changes (280, 380, and 480 mOsm/L) was studied both in proliferating, de-differentiated chondrocytes grown in adhesion, and in differentiated chondrocytes grown in a 3D culture system. To this aim, cell proliferation (cell counting), morphology (optical microscopy), and differentiation (gene expression of specific markers) were monitored along with the expression of osmolyte transporters involved in volume regulation [betaine-GABA transporter (BGT-1), taurine transporter (SLC6A6), and neutral amino acid transporter (SNAT)] real-time qPCR. Proliferating chondrocytes cultured under hyperosmolar conditions showed low proliferation, spheroidal morphology, a significant reduction of de-differentiation markers [collagen type I (Col1) and RUNX2] and an increase of differentiation markers [collagen type II (Col2) and aggrecan]. Notably, a persistently high level of BGT-1 gene expression was maintained in chondrocyte cultures at 380 mOsm/L, and particularly at 480 mOsm/L both in proliferating and differentiated chondrocytes. These preliminary data encourage the study of osmolarity as a microenvironmental co-factor to promote/maintain chondrocyte differentiation in both 2D and 3D in vitro culture systems.

The research article explores how osmolarity impacts the de-differentiation of horse articular chondrocytes during cell expansion in vitro, providing key insights for cartilage repair in tissue engineering.

Research Objective

  • The study aims to investigate how changes in osmolarity, a condition related to the concentration of a solution, influence the de-differentiation of horse articular chondrocytes – the cells that make up cartilage. This is critical for understanding joint diseases and osteoarthritis in equine athletes and for developing new regenerative treatments.

Research Methodology

  • The response of horse articular chondrocytes to varying osmolarity levels (280, 380, and 480 mOsm/L) was studied.
  • Both proliferating, de-differentiated chondrocytes grown in an adherent state and differentiated chondrocytes grown in a 3D culture system were studied.
  • Cell proliferation, morphology, and differentiation were monitored, including the gene expression of specific markers. The expression of osmolyte transporters involved in volume regulation was also studied.

Key Findings

  • Chondrocytes cultured under hyperosmolar conditions showed reduced proliferation, spheroidal morphology, a significant decrease of de-differentiation markers, and an increase of differentiation markers.
  • Specifically, hyperosmolar conditions led to a decline in collagen type I (Col1) and RUNX2 (markers of de-differentiation), and an increase in collagen type II (Col2) and aggrecan (markers of differentiation).
  • A persistently high level of betaine-GABA transporter (BGT-1) gene expression, involved in volume regulation, was maintained in chondrocyte cultures at higher osmolarity levels (380 and 480 mOsm/L).

Implications of the Research

  • The study provides encouraging preliminary data for further research into the role of osmolarity as a key factor influencing chondrocyte differentiation in both 2D and 3D in vitro culture systems.
  • Understanding how osmolarity impacts chondrocyte de-differentiation could improve regenerative therapies aimed at promoting articular cartilage repair after damage.
