May 25, 2024 · Cell theory states that the cell is the fundamental structural and functional unit of living matter. In 1839 German physiologist Theodor Schwann and German botanist Matthias Schleiden promulgated that cells are the “elementary particles of organisms” in both plants and animals and recognized that some organisms are unicellular and others multicellular.

6 days ago · The cell theory is formulated in the first place thanks to observations and formulations of Theodor Schwann (physiologist) and Matthias Schleiden (botanist) . In 1838, Schleiden formulated that all plants are made up of cells, a statement that his colleague Schwann also extended to animals, thus arriving at the first two principles of current ...
May 11, 2024 · Transplantation of Schwann cells/Schwann cell-like cells has emerged as a promising cellular therapy to reconstruct the microenvironment and facilitate peripheral nerve regeneration. In this review, we summarize the role of Schwann cells and recent advances in Schwann cell therapy in peripheral nerve regeneration.
