CO OZNACZA SŁOWO STEM CELL
Komórka macierzysta
Komórki macierzyste są niezróżnicowanymi komórkami biologicznymi, które mogą różnicować się na wyspecjalizowane komórki i mogą dzielić się na produkcję większej liczby komórek macierzystych. Znajduje się w organizmach wielokomórkowych. U ssaków istnieją dwa szerokie rodzaje komórek macierzystych: embrionalne komórki macierzyste wyizolowane z wewnętrznej masy komórkowej blastocystów i dorosłych komórek macierzystych, które znajdują się w różnych tkankach. W organizmach dorosłych komórki macierzyste i komórki progenitorowe działają jako system naprawczy dla organizmu, uzupełniający tkanki dorosłe. W rozwiniętym zarodku komórki macierzyste mogą rozróżnić wszystkie wyspecjalizowane komórki - ektodermy, endodermy i mezodermy, ale także utrzymują normalne obroty narządów regeneracyjnych, takich jak krew, skóra lub tkanki jelitowe. Istnieją trzy znane dostępne źródła autologicznych dorosłych komórek macierzystych u ludzi: ▪ szpik kostny, który wymaga ekstrakcji przez żniwo, czyli wiercenia w kości, ▪ tkanki tłuszczowej, która wymaga ekstrakcji przez liposukcję i ▪ krew, która wymaga ekstrakcji przez aprocesję , w którym krew jest pobierana z dawcy i przechodzi przez maszynę, która ekstrahuje komórki macierzyste i zwraca inne pozostałości krwi dawcy.
