Sources of stem cells
1. Embryonic stem cells
The most common source of stem cells is extracting it from the human bone marrow and reintroducing it to the body. The process is painful and expensive.
Other sources are from a human embryonic cell (fetus) and placenta, whose developing organs and tissues contain large amounts of stem cells.
Still, it is controversial and unethical even if fertilized in vitro. The umbilical cord is also a good source of these cells, but these are still expensive procedures.
2. Pluripotent Stem Cells
Pluripotent Stem Cells, or PSCs, are called “master cells” because they can produce other cells from our three basic body layers. These are the Ectoderm (Skin & Nervous System), Endoderm (Gastrointestinal, respiratory, glands, liver, and pancreas), and Mesoderm (bone, cartilage, circulatory, muscles, etc). The PSC can produce any cell or tissue the body needs to repair itself.
3. Fibroblast Growth Factor
Instead of sourcing pluripotent cells from the bone marrow or the human embryo, an avian embryo can provide a protein called Fibroblast Growth Factor or FGF. Laminine’s young tissue extract (YTE), called Fertilized Avian Egg Extract (FAEE), contains FGF.
Stem cell architect – FGF
FGF acts in an autocrine or paracrine manner interacting with its specific receptors and has been shown to play an important role in tissue formation. When a person undergoes stem cell therapy, his body is first injected with Fibroblast Growth Factor.
FGF plays a crucial role in stem cell work. FGF directs the stem cell where to go and what to repair, likened to an architect.
Signaling proteins are growth factors or FGF
For stem cells to work, it needs adequate protein nourishment. But even with both stem cells and protein materials, it still needs signaling proteins to mobilize it.
One illustration of how it works is blood cells. We have billions of these cells that die each day. Despite it, blood cells thrive as new ones are continually generated, beginning with signaling proteins.
These signaling proteins are the growth factors or FGFs (fibroblast growth factors). They bind to specific receptors on the surface of cells and trigger a cascade of cellular responses that ultimately promote cell growth, proliferation, and differentiation. [Roles of FGF]
The ingredient of Laminines possesses the necessary amino acid and growth factor that makes it effective in helping the body heal itself.
However, the specific function of each FGF family member in vivo has not been fully established. [Bikfalvi et al., 1997]
