Todays regenerative medicine practices likeplatelet rich plasma (PRP) therapyoradipose derived stem cells (ADSC) is predicated on replacing damaged cells through differentiating stem cells, transforming them into new, operational skin, muscle, or bone cells. Vorticella also has an unbranched stalk that anchors its body on a solid object. This is due to their symbiotic relationship with algae. In respect to this, what type of protist is Spirostomum? The Stentor macronucleus contains so many copies of chromosomes (tens of thousands or higher, various by species) that its highly likely that a small piece will contain the necessary genetic information to create a new individual.
