In vitro differentiation of human umbilical cord Wharton’s jelly mesenchymal stromal cells to insulin producing clusters

Figure 5 Morphological differentiation of insulin producing clusters from Wharton’s jelly derived mesenchymal stromal cells in different stages (A-D × 100). A: WJ-MSCs were typically an adherent spindle shape; B and C: The cells gradually formed clusters in the medium 14 d after differentiation; D: At the end of final stage clusters were floated in the medium. WJ-MSCs: Wharton’s jelly derived mesenchymal stromal cells.
