Meirelles et al. considered that the panel of markers may be adjusted in MSC obtained from non- bone-marrow sources [ 8].
"Natural gamma-rays account for about half the dose (of background radiation) reaching children's bone marrow from all sources.
Apart from the bone marrow the source of MSCs may also be the synovial fluid, periosteum, adipose tissue and partly also muscular tissue [ 8, 19].
We compared the adipogenic potential of MSC originated from two adult sources as fat pads and bone marrow, and from four foetal sources as umbilical cord blood, Wharton's jelly, amniotic fluid and preterm umbilical cord perivascular cells.
The result of our rather more simplistic estimation approach (17%) is very similar, despite the assumption that the bone marrow dose of radiation from natural sources is constant throughout life.
Although comparative studies of macrophage behavior with respect to cell source have been conducted, there has been no direct comparison of the three most commonly used cell sources: murine bone marrow, human monocytes from peripheral blood (PB), and the human leukemic monocytic cell line THP-1, across multiple macrophage phenotypes.
We derived average organ doses for brain and red bone marrow (mGy) from local 33 and international sources.
Although the majority are sourced from registered bone marrow donors, a growing proportion are increasingly sourced from previously collected umbilical cord blood (Cutler and Ballen 2012).
Hematopoietic stem cells are the source in the bone marrow from which a constant stream of red and white blood cells is produced throughout a person's life.
And the stem cells would be drawn from a variety of sources other than embryos, like a person's blood or bone marrow, or from mice or monkeys.
There is increasing evidence that mesenchymal stromal cells from bone marrow and other sources including term placenta or adipose tissue are not a homogenous cell population.
