Tras la huella de las células madre

in past years there was an increasing interest by to know about the biodistribution of stem cells in organism after its perfusion or direct injection in a part of the body. thus, we used different procedures including the cell labeling with distinct fluorochromes, such as the green fluorescence protein and the red fluorescence protein or a plasmid transfection codifying the fluorescent proteins of fluorescent molecular stents to identify the chromosomes. recently non-invasive leading imaging techniques have been introduced including nuclear magnetic resonance. as well as procedures based on radionuclide labeling to obtain the positron emission tomography (pet) images or by photon-emission computed tomography (spect).
