Fig. 2From: Donor age effects on in vitro chondrogenic and osteogenic differentiation performance of equine bone marrow- and adipose tissue-derived mesenchymal stromal cellsSafranin-O images of chondrogenic induced cells. Panel showing representative Safranin-O stained pellets of bone marrow (BM)- and adipose tissue (AT)-derived mesenchymal stromal cells (MSCs), and dermal fibroblasts (DF) from horses in five different age groups after 21 days of culture in chondrogenic induction medium. All images are taken under 5 × magnifications. The size-bar on the images is equivalent to 250 µmBack to article page
