Differentiation Potential

Dental tissue-derived mesenchymal stem cells (DT-MSCs) are a promising resource for tissue regeneration due to their multilineage potential. Despite accumulating data regarding the biology and differentiation potential of DT-MSCs, few studies have investigated their adipogenic capacity. In this study, we have investigated the mesenchymal features of dental pulp stem cells (DPSCs), as well as the in vitro effects of different adipogenic media on these cells, and compared them to those of periodontal ligament stem cells (PLSCs) and dental follicle stem cells (DFSCs). DFSC, PLSCs, and DPSCs exhibit similar morphology and proliferation capacity, but they differ in their self-renewal ability and expression of stemness markers (e.g OCT4 and c-MYC). Interestingly, DFSCs and PLSCs exhibited more lipid accumulation than DPSCs when induced to adipogenic differentiation. In addition, the mRNA levels of adipogenic markers (PPAR, LPL, and ADIPOQ) were significantly higher in DFSCs and PLSCs than in DPSCs, which could be related to the differences in the adipogenic commitment in those cells. These findings reveal that the adipogenic capacity differ among DT-MSCs, features that might be advantageous to increasing our understanding about the developmental origins and regulation of adipogenic commitment.

We have examined the initial innervation of the head skin in Xenopus laevis embryos which is by two classes of trigeminal mechanoreceptor with beaded ‘free’ nerve-endings. By recording receptive areas electrophysiologically and staining peripheral sensory neurites with horseradish peroxidase, we have shown that ‘movement detector’ neurites from one trigeminal ganglion do not normally cross the dorsal midline of the head to innervate areas of skin on the opposite side. However, if one trigeminal ganglion is removed before peripheral innervation starts, movement detector neurites from the intact side will now cross the midline to innervate contralateral skin. These observations suggest a specific competitive interaction between movement detector neurites during their innervation of head skin. The second class of receptor, ‘rapid transient’ detectors, have a different pattern of innervation, crossing the midline in both normal and operated animals.
