Hyposalivation resulting from salivary gland dysfunction leads to poor oral health and greatly reduces the quality of life of patients. Current treatments for hyposalivation are limited. However, regenerative medicine to replace dysfunctional salivary glands represents a revolutionary approach. The ability of dispersed salivary epithelial cells or salivary gland-derived progenitor cells to self-organize into acinar-like spheres or branching structures that mimic the native tissue holds promise for cell-based reconstitution of a functional salivary gland. However, the mechanisms involved in salivary epithelial cell aggregation and tissue reconstitution are not fully understood. This study investigated the role of the P2Y2nucleotide receptor (P2Y2R), a G protein-coupled receptor that is upregulated following salivary gland damage and disease, in salivary gland reconstitution. In vitro results with the rat parotid acinar Par-C10 cell line indicate that P2Y2R activation with the selective agonist UTP enhances the self-organization of dispersed salivary epithelial cells into acinar-like spheres. Other results indicate that the P2Y2R-mediated response is dependent on epidermal growth factor receptor activation via the metalloproteases ADAM10/ADAM17 or the α5β1integrin/Cdc42 signaling pathway, which leads to activation of the MAPKs JNK and ERK1/2. Ex vivo data using primary submandibular gland cells from wild-type and P2Y2R−/−mice confirmed that UTP-induced migratory responses required for acinar cell self-organization are mediated by the P2Y2R. Overall, this study suggests that the P2Y2R is a promising target for salivary gland reconstitution and identifies the involvement of two novel components of the P2Y2R signaling cascade in salivary epithelial cells, the α5β1integrin and the Rho GTPase Cdc42.

Cell aggregates formed during the first 2 days of culture of cells derived from hair folIicle tissue of young rats. Aggregates occurred at an accelerated rate at higher cell densities, and contained a high proportion of epithelial cells although a variable proportion of esenchymal (fibroblast) cells were present. Citrulline was detected in the cultured cell proteins. Electrophoretic analysis of the proteins showed the presence of hair cortical keratin in the cultures, but these proteins were not synthesized during the culture period, in conflict with previous findings.

Selective enterocyte transplantation may be an alternative to whole organ transplantation for increasing absorptive capacity. Our aim was to determine the effect of initial cell number and viability, proportion of intact crypts, and basement membrane components (BMC) on the in vitro growth of rabbit enterocytes. Enterocytes were harvested using warm trypsinization from ileal segments in 40 rabbits. Initial cell viability was 92 ± 4% (mean ± SD), cell yield was 7.7 ± 3.6 × 106 cells/cm, and there were 0.51 ± 0.33 crypts/100 cells. Initial cell viability correlated with cell yield (r = −0.508, p < 0.001) and % crypts (r = 0.313, p < 0.05). Cell yield also correlated with % crypts (r = −0.645, p < 0.001). Enterocytes (5 × 106) were incubated in growth media in plain or BMC coated growth culture vessels for 14 days. There was a correlation between both number of cells seeded (r = 0.824, p < 0.001) and cell viability (r = −0.696, p < 0.01) and % growth colonies containing epithelial cells at 14 days. Both total growth colonies (r = −0.565, p < 0.05) and colonies with epithelial cells (r = −0.589, p < 0.05) had a negative correlation with % crypts. Incubating cells in BMC coated vessels (n = 6) resulted in significantly more dispase liberated cells after 14 days than in plain vessels (n = 6) (6.6 ± 1.1 vs. 3.8 ± 1.0 × 106, p < 0.05) but viability was similar (97 ± 2% vs. 96 ± 2%). Diamine oxidase (DAO) activity was significantly increased in the growth media of cells cultured on BMC compared to controls (0.76 ± 0.24 vs. 0.43 ± 0.28 units, p < 0.05) although DAO act/cell was similar. Conclusions: 1) cell yield using warm trypsinization is increased at the expense of viability and intact crypts; 2) in vitro growth is increased by increasing the number of cells but not intact crypts seeded; 3) BMC increase the yield of cells with viability and maturity similar to those cultured in plain vessels.
