hi snowshredder,
while this is definitely an interesting articel it is not right at all (have also read it at hypeandhope.com):
The discovery is a landmark achievement for adult stem cell research because its the first time adult stem cells have been purified from an adult tissue other than bone marrow or blood.
look at www.ifats.org a scientif community which is researching fat tissue as a source for stemcells for some time now.
let me give you the following quotation from a scientif report which compares the regenerative qualities of stem cells derived from bone marrow and those derived from fat tissue:
"Adipose, also known as fat tissue is the richest and most accessible known source of stem cells:
The volume of human marrow taken under local anesthesia is generally limited to no more than 40 ml. This 40 ml of marrow will contain approximately 2:4 x 104 MSCs in a skeletally mature adult. Obtaining a larger volume necessitates the use of general anesthesia, in-creases donor site morbidity, and further dilutes the stem cell fraction with stem cell-free blood.
By contrast, a typical harvest of adipose tissue, under local anesthesia, can easily exceed 200 ml. This 200 ml lipoaspirate will typically yield in excess of 1 X 106 stem cells; a differen-tial of approximately 40-fold more than that present in 40 ml of marrow.
ADAS contains a specialized class of stem cells comprised of multiple cell types that promote healing and repair. Adipose stem cells have been shown to differentiate into multiple cell types, including muscle cells (heart, smooth and skeletal) bone, fat, cartilage and nerve. Beyond differentiation, regenerative cells may provide therapeutic benefit through the release of growth factors and other therapeutic healing mechanisms.
