The reprogramming of differentiated cells into stem cells and some other applications, opened the door to a new age of regenerative medicine. Regulatory, medical, and aesthetic aspects are on the agenda. Both in theory and reality, a controlled cultivation of the embryonic and pluripotent stem cells from the stratified (dissected) cells has long been considered to be impossible.

Polydactyly is a medical term referred to having extra finger or toe. It is an inborn condition connected with disturbances of the limb formation due to genetic or external influences. Influences in early pregnancy are the most significant, as the digits are already recognizable at 41-43 days of gestation and are completely formed at 53 days.

Stem cell usage is one of the most perspective medical fields. In Germany and other developed countries, huge amounts of money are invested in the research and development of this field, since in the future, it will allow the curing of many diseases which are still incurable. However, not many people are interested in the future.

Immunotherapy is one of the most effective treatment options for lymphoma. It is used in combination with chemotherapy and has also become a life-saving treatment for many patients whose tumor has recurred and chemotherapy is no longer working. Some types of immunotherapy are so effective that they can even cure aggressive end-stage lymphomas.

Over 400,000 new cases of bladder cancer are diagnosed in the world annually. In 75% of patients, the tumor is detected at an early stage. However, in every fourth person it is detected when it is at the stage of invasive bladder cancer, after lymph node lesions are present, or after the appearance of distant metastases.

The medical term, "pulmonary hypertension" comprises of an increasing pressure in the lung vasculature or pulmonary circuit. This pathological process is peculiar to the progressing increase of vascular resistance. These changes can often lead to failure of the right ventricular and consequently the untimely death of a patient.

Regenerative cell medicine uses stem cells (SCs) to repair damaged bone marrow, nerve tissue, the musculoskeletal system, or to generally rejuvenate a person. With careful harvesting and processing in laboratory conditions, SCs can become the source of most types of differentiated cells in an adult organism.

Immunotherapy is the most rapidly developing area of cancer treatment in the 21st century. Many methods and drugs have already been approved that significantly improve the results of cancer therapy, especially in the advanced stages. Immunotherapy causes immune cells to attack cancer cells more actively.
