Very few clinics make any attempt to count these total cells. 2. CFUs are helpful, but only as a qualitative rough metric, not as an exact count of anything. WebGo to: Definition White blood cells (WBC) are a heterogeneous group of nucleated cells that can be found in circulation for at least a period of their life. Their normal concentration in blood varies between 4000 and 10,000 per microliter. They play a most important role in phagocytosis and immunity and therefore in defense against infection.

WebBut, CD34+ counts are not an accurate measure of stem cells: CD34+ results vary between labs, they can vary within a single lab, and only 1-2% of the MNC that have CD34+ are actually stem cells.

Reactive dyes are used to distinguish dead cells from live cells. Examples are trypan blue or propidium iodine, which stain dead cells but not live cells. For these two dyes: viability = (total cells – dye positive cells)/total cells = dye negative cells/total cells. What is a nucleated cell count?

WebCells are starved in serum-free media for 24 h to quiesce and synchronize cells in the G1 phase of the cell cycle. VSMCs are then stimulated with a mitogen such as 10–15% serum. At varying time points poststimulation (usually 24–72 h), the cells are counted. For human VSMCs, we find that the doubling time is ∼48 h.
