Amount within a generates up to 80% of the total dry mass of the cell and whole protein amount of a cell population correlates well with the number of cells. By using suspended cells, we were able to determine dry mass and volume for single cells. Interestingly, we observed a moderate increased in dry mass upon EGF stimulation as compared to the dry mass of unstimulated cells while BMN673 mitomycin c treatment resulted in highly significantly increased cellular dry mass. This finding is in line with a study by Mir et al. demonstrating that human osteosarcoma U2OS cells double their dry mass before entering mitosis and detecting that daughter cells possess exactly one half of the parental cell mass. The high increase in dry mass of mitomycin c-treated cells is most likely the result of the mitosis inhibitory effect of this agent. Consequently, the wound closure of EGF-treated cells was accelerated as compared to untreated cells and cells treated with mitomycin c. In, it is reported that the cellular dry mass is directly dependent on the growth rate. Moreover the accuracy of optically assessed cellular dry mass by quantitative phase imaging as well as the possibility to quantify cell growth noninvasively by optical imaging alone has nicely been demonstrated earlier.Furthermore, drugs that eliminate the inhibitory environment or enhance the regenerative ability of axons could also be included. Second, the present NT-3 delivery system is safe. Both PCLA and SF are recommended scaffold materials because of their unique features, such as biocompatibility and biodegradability, for tissue engineering for the repair and regeneration of injured tissues. Astaxanthin is a superb antioxidant and a natural food coloring agent that has been used in nutraceutical, aquaculture, and poultry industries. Among the naturally occurring organisms capable of producing astaxanthin, the unicellular microalga Haematococcus pluvialis can accumulate the largest amounts under various adverse environmental or culture conditions. Over the past two decades, mass culture of H. pluvialis in photobioreactors has been exploited to produce natural astaxanthin.
