Multipotent mesenchymal stromal cells also known as mesenchymal stem cells according to the signal from the damaged tissue have the ability to differentiate into several types of specialized cells forming tissues of mesodermal origin such as bone, cartilage, tendon, skeletal muscle or adipose tissue. This ability of MSC is used in regenerative medicine. For the clinical and experimental purposes in order to increase the amount of MSC their ability to proliferate in vitro is used. The best-known source of mesenchymal stem cells is the adipose tissue and bone marrow which is the most common source material used for primary culture. This paper presents the next steps of culturing mesenchymal stem cells in vitro.

Mesenchymal stem cells (MSCs) have remarkable immunomodulatory properties, low immunogenicity, and paracrine properties as well as the ability to differentiate into multiple cell lines. These properties make them potential candidates for clinical applications in the treatment of neurodegenerative, cardiovascular, and lung diseases, which may be occupational diseases. Preclinical studies using experimental animal models have demonstrated regenerative properties of MSCs in diseases such as silicosis and occupational asthma. Currently, treatment of the novel disease COVID-19 could be enhanced by using MSC therapies. This disease affects many professional groups with great intensity and its consequences might be considered as an occupational disease. It is a significant public health problem and a therapeutic challenge. Despite the development of vaccines against COVID-19, there is growing concern about the emergence of new mutations of the SARS-CoV-2 virus in addition to the known alpha, beta, gamma, and delta variants. There is still no effective COVID-19 treatment and the existing ones only play a supporting role. MSCs offer treatment possibilities as an alternative or complementary therapy. The clinical trials to date using MSCs in patients with COVID-19 give hope for the safe and effective use of this stem cell population.
