The in vivo (vital) method of staining some blood cells leaving the blood vessels is based on their ability to absorb the dye injected subcutaneously, which is not destroyed in the body.  What is the name of the tissue form of existence of these cells?  What is the name of the dye absorption process?

In biology, tissue is a biological organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

What is the tissue?

American scientists restored the heart muscle by obtaining its cells from connective tissue.  Connective tissue cells were "reprogrammed" with viral vectors, and as a result, normal cardiomyocytes developed from them.  The results of this study and some other works testify to the success of regenerative methods in biology and medicine.
