PARTICIPATION OF 'NON-MUSCLE' STEM CELLS IN REGENERATION OF SKELETAL MUSCLE

Skeletal muscle tissue is characterized by ability to regenerate in response to injury resulting for example from mechanical trauma, toxin or disease. The key role in this process is played by satellite cells localized in skeletal muscle. However, both under physiological and experimental conditions different types of stem cells originating either from skeletal muscle or other tissues can be also involved in regeneration. This raises the hope for potential use of stem cells in the therapy for skeletal muscles diseases, such as muscular dystrophies or spinal muscle atrophy.

INDUCED PLURIPOTENT STEM CELLS HOPES, FEARS AND VISIONS

In 2006 first paper describing reprogramming of fibroblast into pluripotent cell, i.e. one that is able to differentiate into all tissues was published. Before that spectacular achievement many projects devoted to study the mechanisms of cell de-differentiation led to the establishment of animal cloning techniques and also derivation of embryonic stem cell lines. Present review summarizes the history of these studies and also describes pioneer works leading to derivation of induced pluripotent stem cells, current methods of reprogramming, and possible applications of these cells.

Score human stem cells participate in the regeneration of skeletal muscle? mouse model study

SCID mice ability to accept grafts ksengenicznch, allows the study of human stem cells share tissue regeneration. Regeneration of skeletal muscle is a good model for the study of stem cell involvement in the process. Regeneration of skeletal muscles depends on the presence of satellite cells (muscle precursor cells). Apart from them can participate in the regeneration of stem cells from other tissues. The aim of the project is to investigate what might be involved in the regeneration of stem cells in a xenograft system.
