WNT16 induces proliferation and osteogenic differentiation of human perivascular stem cells

Abstract

Perivascular stem cells (PSC) are a progenitor population defined by their perivascular residence. Recent studies have examined the relative difference in Wnt ligands to induce PSC differentiation, including Wnt16. Here, we examine the role of Wnt16 in the proliferation and osteogenic differentiation of human PSC. Treatment of PSC with WNT16 significantly increased cell proliferation to a greater extent than did WNT3A. In addition, WNT16 showed a significant increase in osteogenic gene expression among PSC. These data demonstrate that WNT16 represents a combined mitogenic/pro-osteogenic stimulus that may play a functional role in human mesenchymal stem cell mediated bone repair.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

CZI Human Cell Atlas Seed Network

The aim of the Human Cell Atlas (HCA) is to build reference maps of all human cells in order to enhance our understanding of health and disease. The Seed Networks for the HCA project aims to bring together collaborators with different areas of expertise in order to facilitate the development of the HCA.
