Adhesion in the world of plants and animals

"Wszechświat" vol. 120, No. 4-6 / 2019

The article describes the physical phenomenon of  adhesion, discussing factors affecting adhesion such as surface tension. Next, the article shows where in the world of plants or animals we can observe adhesion. Finally, the practical use of the above knowledge is discussed.

Application of dental pulp stem cells in neural tissue regeneration

Dental pulp stem cells (DPSCs) are a population of cells residing in mammalian dental canals. These multipotent cells show the morphology and expression of surface markers of mesenchymal stem cells: CD29, CD44, CD90, CD73. In addition, they are negative for antigens characteristic for hematopoietic stem cells such as CD45 or CD34. Their advantages are the non-invasive collection procedure and high proliferative potential. In addition, DPSCs undergo osteogenic, chondrogenic, adipogenic differentiation and due to their ectodermal origin they can also be used in the regeneration of nervous tissue. The aim of the study is to review of literature addressing possibilities of using dental pulp stem cells in the regeneration of nervous tissue. Dental pulp stem cells can be used in the regeneration of nervous tissue in both undifferentiated state through paracrine effects and also after differentiation into neurons. This process takes place in two stages with the neurospheres stage. DPSCs after differentiation show increased expression of neural cell markers and reduced expression of nestin – protein characteristic of neural stem cells, what confirms their differentiation. Using stem cells gives hope for reducing the effects of the disease for people after ischemic stroke as well as for patients suffering from neurodegenerative diseases. Dental pulp stem cells due to their ectodermal origin become an attractive alternative to other types of stem cells, such as stem cells derived from the bone marrow or umbilical cord stem cells in their use in the regeneration of damaged nervous tissue.
