Although after 48 hr most O4+ cells were bipolar, we found more branching after 4 days; after 7 days of differentiation, multipolar and membrane sheet-forming cells were prominent.
Above, we demonstrated the presence of functional TJ in the mature 3 5 layered epithelial sheet formed by RCE1 5T5) cells.
Morphological, molecular and physiological analysis showed that the epithelial sheet formed by RCE1 5T5) cells possessed TJs similar to those found in vivo.
Since the surface contact was not formed, cells formed into an intact cell sheet after 2 days, as shown in Figure 8(b).
HUVECs seeded on the hMSCs cell sheet formed rich networks, while on the tissue culture plate, no networks formed.
The hMSCs was chosen to form cell sheet matrix due to its stabilization ability for new-formed blood vessels as a pericyte and the osteogenic differentiation potential.
We first cultured human mesenchymal stem cells (hMSCs) to form cell sheet and human umbilical vascular endothelial cells (HUVECs) were then seeded on the undifferentiated hMSCs sheet to form vascularized cell sheet for mimicking the fibrous layer of native periosteum.
Next, they layered single-cell sheets to generate bilayer-cell sheets, forming an electrically communicative three-dimensional cardiac construct, which exhibited spontaneous and synchronous pulsation with electrical communication between the cell sheets, mediated by connexin 43.
Briefly, ASC and DF were cultured with ascorbate to form cell sheets subsequently rolled around a mandrel.
Dental follicle cells (DFCs) are believed contain the precursor cells of the periodontium and can form cell sheets by secreting extracellular matrix (ECM) proteins.
For validation, polydimethylsiloxane (PDMS) of different combinatorial substratum properties (including stiffness, roughness and wettability) were created, on which the human bone marrow derived mesenchymal stem cells (BMSCs) were cultured to form cell sheets with their multipotency evaluated after induced differentiation.
