Morphological and Molecular Analysis of In Vitro Tubular Structures from Bovine Yolk Sac-Derived MSCs

Figure 4

Photographs and photomicrographs of xenotransplant tissue generated by bYS-MSCs in immunosuppressed mice (nude). (a) Tissue prior to xenotransplantation (40x); (b) abdominal incision with tissue (arrow); xenotransplanted tissue (b); (c) gastrointestinal organ “ex situ,” observe the lack of growth of the structures in this region. Large intestine (li), jejunum (J), mesentery (m), and small intestine (si); (d, e) the mesentery (ms) and the suture in the tissue generated by the MSC center node (arrows); (f–k) HE staining and toluidine blue, note the collagen fibers (arrow) and elastic (thin arrow).
