Where can knowledge about cells and tissues be applied?

Cytology and histology have been developing for over a hundred years. During this time, we have figured out many molecular mechanisms. A lot is given to us by knowledge about DNA, which today can be edited using gene therapy. Knowing the peculiarities of the course of cell metabolism, it is possible to determine with what certain diseases are associated. By studying the cells of bacteria or algae, you can extract useful substances from them. And even today, the cultivation of artificial organs and tissues is developing in transplantation.
