Ploidy Manipulation of Zebrafish Embryos with Heat Shock 2 Treatment

Abstract:
The evidence provided in our laboratory on somatic polyploidy is reviewed. The development of some embryonal cell populations being taken as an example, the main problems of somatic polyploidy are discussed: somatic polyploidy and proliferation, growth, cell differentiation and specialization, the significance of polyploidy in the development of embryonal populations, in the realization of development programs etc. The term "somatic polyploidy" is not thought to involve the complex of phenomena it designates. A new, more precise and general concept is proposed--"hyperreplication of DNA", which seems to cover indeed the whole complex of phenomena characterizing the increase of DNA content in the nuclei of somatic cells including the polyploid ones.
