- Well perhaps, then again perhaps not.

- There is no doubt that the cell(s) are living, and biologically
- human, but as for becoming something else ...

- Cancer Cells vs. Embryonic cells
-
- Observation:
- cancer cells spread in a manner resembling embryonic cell
- migrations.
- Barbera et al.-- demonstrated specific adhesive
- recognition may control homing of optic nerves
- from retina to optic tectum
- Nicolson et al.-- demonstrated that cells from primary
- tumors for secondary tumors at sites where those cells
- have greatest adhesion.
-
- have greatest adhesion.
-
- Question:
- do we have embryo-like tumors or tumor-like Embryos?
- Mintz et al.--isolated teratoma cells, injected the
- cells into early blastocysts (mice). The blasocysts
- were allowed to implant into the uteri of other
- female mice (different genotype from cancer donor).
- embryos developed into tumor free adults, but with
- cells of both genotypes.
-
- also observed:
- (mouse)teratomas develop in clusters that
- resemble (mouse) embryos & will differentiate
- into the embryonic tissue types if in a
- suitable environment.
-
- normal (mouse) embryos will form teratomas if
- implanted in the testes.
-
- Now, if cancer cells can develop as an embryo does if placed in a
- receptive uterus (suitable environment) and an embryo can develop
- as a cancer if placed in an unsuitable environment, then are you
- sure that an embryo can't change form?
