[Does mechanical tension regulate the development of muscular rudiments?].

G Filogamo, M G Giacobini Robecchi

    Bulletin De L'Association Des Anatomistes
    |September 1, 1985
    PubMed
    Summary

    Limb bud removal in chick embryos altered pectoral muscle development. Early changes involved growth and differentiation, alongside observed regressive processes in the affected limb.

    Area of Science:

    • Developmental Biology
    • Regenerative Medicine
    • Embryology

    Context:

    • Limb bud development is crucial for appendage formation.
    • Understanding limb regeneration informs therapeutic strategies.
    • Chick embryos serve as a model for vertebrate development.

    Purpose:

    • To investigate the impact of limb bud destruction on pectoral muscle development.
    • To analyze cellular and tissue-level changes post-amputation.
    • To study mitotic activity and differentiation in developing muscle.

    Summary:

    • Destruction of the right anterior limb bud in chick embryos led to observable changes in pectoral muscle growth.
    • Both growth, differentiation, and organogenesis were affected, with some regressive processes noted.
    • Electron microscopy and autoradiography revealed early, frank alterations in muscle tissue.

    Impact:

    • Provides insights into the complex interplay of growth and regression during embryonic development.
    • Contributes to the understanding of limb development and potential regenerative mechanisms.
    • Highlights the sensitivity of muscle development to early embryonic insults.
