The effect of ascorbic acid on a proliferating cell system

B Iyengar, S K Lal

    International Journal of Tissue Reactions
    |January 1, 1982
    PubMed
    Summary

    Ascorbic acid stunts early chick embryo development by harming resting cells and reversing differentiation. Copper sulfate counteracts these effects, protecting the embryo, suggesting therapeutic potential for vitamin C in neoplasia.

    Area of Science:

    • Developmental biology
    • Cell biology
    • Biochemistry

    Background:

    • Ascorbic acid (vitamin C) plays crucial roles in cellular processes.
    • Early embryonic development is highly sensitive to biochemical insults.
    • Neoplasia involves uncontrolled cell proliferation and differentiation abnormalities.

    Purpose of the Study:

    • To investigate the effects of ascorbic acid on early chick embryo development.
    • To determine the role of copper sulfate in mitigating ascorbic acid's effects.
    • To explore potential parallels between embryonic development and neoplasia.

    Main Methods:

    • Injection of ascorbic acid and copper sulfate into the sub-blastodermal space of early chick embryos (17 hours incubation).
    • Observation and analysis of embryonal axis stunting and cellular changes.
    • Comparative analysis of ascorbic acid alone versus in combination with copper sulfate.

    Main Results:

    • Ascorbic acid induced marked stunting of the embryonal axis.
    • Absence of interphase cells suggests ascorbic acid is lethal to resting cells and causes differentiation reversal.
    • Copper sulfate counteracted the detrimental effects of ascorbic acid when administered prior.

    Conclusions:

    • Ascorbic acid exhibits teratogenic effects on early chick embryos, impacting cell viability and differentiation.
    • Copper acts protectively against ascorbic acid-induced developmental toxicity.
    • The findings suggest a potential therapeutic role for vitamin C in managing conditions like neoplasia.
