Abstract:
NELL-1 is an osteogenic protein first discovered to control ossification of the cranium. NELL-1 exists in at least two isoforms. The full-length NELL-1 contains 810 amino acid (aa) (NELL-1810), the N-terminal-truncated NELL-1 isoform contains 570 aa (NELL-1570). The differences in cellular effects between NELL-1 isoforms are not well understood. Methods: Here, BMSC were derived from adult or aged mice, followed by overexpression of NELL-1810 or NELL-1570. Cell morphology, proliferation, and gene expression were examined. Results/Conclusions: Overall, the proliferative effect of NELL-1570 was age dependent, showing prominent induction in adult but not aged mice.
