these stem cells become specialised and develop into heart muscle cells.(4)___(b) Explain the advantages of using stem cells from the patient instead of using stem cells from a donor.(2)(c) Suggest why this form of stem cell therapy is less controversial than embryonic stem cell therapy....
Who discovered bone marrow? What are somatic stem cells? What are somatic stem cells used for? Can bone marrow be donated after death? What part of a bone produces blood cells? Where do adult somatic stem cells originate? What does hypercellular bone marrow mean?
where the stem cells would "transplant" themselves to occupy, differentiate, and thus repair damage. However,further studiesshowed that their action is paracrine. They secrete growth factors and cytokines, among other molecules, and are responsible for their therapeutic bene...
Stem cells are collected with an apheresis machine from the blood flowing through a catheter, which is inserted into a vein. Blood flows from a vein through

根据第三段“Through experiments involving X-rays and chemicals, they discovered that stem cells were more sensitive to DNA damage compared to other cells.(通过涉及x射线和化学物质的实验,他们发现干细胞比其他细胞对DNA损伤更敏感)”可知,植物中的干细胞对DNA损伤做出快速反应。故选C。 (3)题详解: ...
Until recently, it was thought that once a cell had acquired a stable differentiated state, it could not change its phenotype. We now know this is not the case, and over the past few years a plethora of well-documented examples have been presented whereby already differentiated cells or ...
The bioengineered immune players called CAR T cells last longer and work better if pumped up with a large dose of a protein that makes them resemble stem cells.
After 20 years of hope, promise and controversy, human embryonic stem cells are reshaping biological concepts and starting to move into the clinic. By David Cyranoski Twitter Facebook Email Dieter Egli was just about to start graduate school in 1998 when researchers first worked out how to ...
