Noggin Antagonizes BMP Signaling to Create a Niche for Adult Neurogenesis
Large numbers of new neurons are born continuously in the adult subventricular zone (SVZ). The molecular niche of SVZ stem cells is poorly understood. Here, we show that the bone morphogenetic protein (BMP) antagonist Noggin is expressed by ependymal cells adjacent to the SVZ. SVZ cells were found to express BMPs as well as their cognate receptors. BMPs potently inhibited neurogenesis both in v...
متن کاملThe vascular niche in adult neurogenesis
Blood vessels (BVs) not only serve as conduits for oxygen and nutrients but may also fulfill perfusion-independent functions. A growing body of data suggests that blood vessels are an integral component of stem cell niches, including stem cell niches in the adult brain. This review summarizes in vivo studies supporting the contention that blood vessels may indeed control function of neuronal st...
متن کاملBone morphogenetic protein (BMP)-6 signaling and BMP antagonist noggin in prostate cancer.
It has been proposed that the osteoblastic nature of prostate cancer skeletal metastases is due in part to elevated activity of bone morphogenetic proteins (BMPs). BMPs are osteoinductive morphogens, and elevated expression of BMP-6 correlates with skeletal metastases of prostate cancer. In this study, we investigated the expression levels of BMPs and their modulators in prostate, using microar...
متن کاملFstl1 Antagonizes BMP Signaling and Regulates Ureter Development
Bone morphogenetic protein (BMP) signaling pathway plays important roles in urinary tract development although the detailed regulation of its activity in this process remains unclear. Here we report that follistatin-like 1 (Fstl1), encoding a secreted extracellular glycoprotein, is expressed in developing ureter and antagonizes BMP signaling activity. Mouse embryos carrying disrupted Fstl1 gene...
متن کاملAdult Neurogenesis: Ultrastructure of a Neurogenic Niche and Neurovascular Relationships
The first-generation precursors producing adult-born neurons in the crayfish (Procambarus clarkii) brain reside in a specialized niche located on the ventral surface of the brain. In the present work, we have explored the organization and ultrastructure of this neurogenic niche, using light-level, confocal and electron microscopic approaches. Our goals were to define characteristics of the nich...
