Stem cells are naïve or master cells. This means they can transform into special 200 cell types as needed by body, and each of these cells has just one function. Stem cells are found in many parts of the human body, although some sources have richer concentrations than others. Some excellent sources of stem cells, such as bone marrow, peripheral blood, cord blood, other tissue stem cells and ...
Despite their high potential to replace the time consuming gold standard blood culture for infection diagnosis from whole blood, molecular biology based techniques often lack sensitivity and specificity due to the high human background in complex biological samples such as blood. Concerning the realization of a point-of-care device for sepsis diagnosis which would enable immediate targeted anti...
