Effects of Severe Hypoxia on Bone Marrow Mesenchymal Stem Cells Differentiation Potential

Figure 4

Histochemical (HE: hematoxylin-eosin; TB: toluidine blue; AB: alcian blue; MT: Masson’s trichrome; SaO: safranin O) and immunohistochemical results for collagen type 2 (Col2A1) cells differentiated toward chondrocytes. The photos are relative to day 14 of cultures in chondrogenic differentiation medium in normoxic conditions (up) and in hypoxic conditions (down).
