Mm. Lieber, FORCE, DEVELOPMENT, AND NEOPLASIA - DEVELOPMENT FROM ANOTHER PERSPECTIVE AS ILLUSTRATED THROUGH A STUDY OF IN-VITRO PLANT DEVELOPMENT FROM NEOPLASM, RIV BIOL, 89(2), 1996, pp. 245-273
Differentiation from the neoplastic state can be a dynamic adaptation
to the localized stress of increasing cohesive forces in tissue. Repul
sive forces, occurring within and between cells, are seen as leading t
o de-differentiation into the neoplastic State or neoplasm. During ear
ly development, especially where and when mitosis occurs frequently, c
ohesive and repulsive forces may necessarily coexist in oscillating de
grees. Correspondingly, cohesive-force and repulsive-force generating
metabolites may co-exist in oscillating concentrations. Cancer or neop
lasia occurs, according A. Szent-Gyorgyi, when cohesiveness breaks dow
n locally, probably thru the conversion of methylglyoxal into lactic a
cid. Cancer may also occur due to the accumulation of such putatively,
repulsion-generating factors as lactic acid Plant tumors in vitro res
pond adaptively to cohesion-generating chemicals, such as ascorbic aci
d and methylglyoxal, by generating buds, embryos, and plantlets.
