Accordingly, within a single branch, the voltage is multiplied by the number of cells that form the branch.
This model integrates prior hypotheses about the link between the subperiderm and feather barbs and barbules [ 11, 20], the key role of the tubular shape of the feather follicle in establishing the complex branching of feathers [ 19, 28] and the role of cell death in removing cells that separate the branches of growing feathers [ 13, 29, 30].
Microglia are non-neuronal cells that have numerous branches and are highly abundant in the brain.
HSC differentiate into common lymphoid (CLP) and common myeloid progenitor (CMP) cells that constitute early branching points of lymphoid and myeloid lineage commitment, respectively [1].
This process has been studied in detail and includes endothelial cell migration towards the concentration gradient of growth factors such as vascular endothelial growth factor [39]. Migration is directed by "leader" endothelial cells that, similarly to branching morphogenesis in other tissues, direct the movement of the cells of the stalk.
The process begins with the proliferation of proximal endothelial cells that form capillary branches, with vessel lumen forming through anastomotic connections between capillary tips (Mustonen and Alitalo, 1995; Risau, 1997).
Podocytes are highly specialized terminally differentiated cells that extend numerous lamellipodia that branch into primary and secondary processes, which further ramify into smaller processes known as foot processes [ 43].
Disruption of cytoskeletal architecture upon treatment resulted in more compact, rounded cells that lacked the extensively branched actin structures normally seen in MDA-MB-231 cells.
Later on the posterior cerebral veins (PCeV) branch from the DLV and ChP cells coalesce beneath that branching point in close contact with the vessels (Fig. 4B, B', D).
GFP+ cells were observed in branching mammary cells that stained also for carmine and other specific marker for luminal (CK18) and myoepithelial (CK14) cytokeratin.
