Abstract Background Reconstruction of complex critical-size defects (CSD) in the craniofacial region is a major challenge, and soft tissue regeneration crucial determining therapeutic outcomes CSD. Stem cells from apical papilla (SCAP) are neural crest-derived mesenchymal stem (MSCs) that homologous to represent promising source for regeneration. Exosomes, which contain compound bioactive compo...

The avian basilar papilla is composed of hair and supporting cells arranged in a regular pattern in which the hair cells are surrounded and isolated from each other by supporting cell processes. This arrangement of cells, in which the apical borders of hair cells do not contact one another, may be generated by contact-mediated lateral inhibition. Little is known, however, about the way in which...

LOVERDE P. T. 1975. Scanning electron microscope observaticns on the miracidium of Schistosoma. International Journal&w Parasitology 5: 95-97. Miracidia of two specirs of Schistosoma, viz. haematobium and juponicum, were studied with the scanning electron microscope to more clearly visualize what is seen with the light microscope and the transmission electron microscope, and more specifically, ...

Stem cells and their nearby niche generate an organ architecture essential to its function. For hair production, the follicle remodels epithelial through stem cell behaviors under instruction of a juxtaposed fibroblast -- dermal papilla. Although papilla’s signaling crosstalk with epithelium is well-characterized, little known about how physical organized support cells. Here, we leveraged live ...
