Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
A polycarbonate is an oxocarbon dianion consisting of a chain of carbonate units, where successive carbonyl groups are directly linked to each other by shared additional oxygen atoms. That is, they are the conjugate bases of polycarbonic acids , the conceptual anhydrides of carbonic acid , or polymers of carbon dioxide .
In cell biology, precursor cells—also called blast cells—are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells .
The third method is cell culture, of which there are three types: (1) precursor cell culture, i.e. undifferentiated cells that are to be differentiate, (2) differentiated cell culture, i.e. completely differentiated cells that have lost the capacity to further differentiate, and (3) stem cell culture, i.e. undifferentiated cells that can ...
The megakaryoblast is derived from colony forming units (CFU-Meg) of hematopoietic stem cells found in red bone marrow. There are biomarkers found on the surface of hemopoietic stem cells that are used as identifiers for megakaryoblasts and other precursor cells. Two of the committed biomarkers are CD34-and CD150+.

Under the pre-cell theory (Kandler 1994ff) [6] [7] [8], based on the Iron-Sulfur world hypothesis (metabolism-first scenario), [9] primordial metabolism led to the early diversification of life through the evolution of a multiphenotypical population of pre-cells, defined by Kandler as metabolizing, replicating loose entities exhibiting many of ...
Polycarbonates do not have a unique resin identification code. Items made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Susceptible to UV light, exposure results in yellowing (degradation is especially visible in headlamps that lost or didn't have proper protective coating).
C2C12 myotubes under light microscope, 10x magnification. C2C12 is an immortalized mouse myoblast cell line.The C2C12 cell line is a subclone of myoblasts that were originally obtained by Yaffe and Saxel at the Weizmann Institute of Science in Israel in 1977. [1]
