It has been demonstrated that reprogramming factors are sequestered in the pronuclei of zygotes after fertilization. because zygotes enucleated at the M phase instead of interphase of the first mitosis can support the development of cloned embryos. However. the contribution of the parental pronucleus derived from either the sperm or the oocyte in reprogramming remains elusive. https://nvmeclothingers.shop/product-category/quinceanera/
