INFLUENCE OF PLANTING DATES AND SOME CHEMICAL SUBSTANCES ON ROOTING OF PHYTOLACCA DIOICA



Defining the ultrastructure of the hematopoietic stem cell niche by correlative light and electron microscopy

The blood system is supported by hematopoietic stem and progenitor cells (HSPCs) found in a specialized microenvironment called the niche.Many different niche cell types support HSPCs, however how they interact and their ultrastructure has been difficult to define.Here, we show that single endogenous HSPCs can be tracked by light microscopy, then i
