The germinal vesicle material required for sperm pronuclear formation is located in the soluble fraction of egg cytoplasm
The chromatin of Xenopus laevis sperm nuclei was induced to decondense, swell and form mitotic chromosomes following its injection into mature Rana pipiens oocytes. In contrast, the sperm chromatin did not decondense or form mitotic chromosomes when injected into oocytes from which the germinal vesi...

520 | |a The chromatin of Xenopus laevis sperm nuclei was induced to decondense, swell and form mitotic chromosomes following its injection into mature Rana pipiens oocytes. In contrast, the sperm chromatin did not decondense or form mitotic chromosomes when injected into oocytes from which the germinal vesicle (GV) was removed prior to the initiation of maturation. Injection into enucleated oocytes of the material extracted from manually-isolated GVs restored their ability to decondense sperm nuclei. This soluble GV material was stable at 18 ^oC for 16 h but was inactivated by heating to 80 ^oC for 10 min. We examined the distribution of this GV material in a cytoplasmic preparation from activated eggs which can induce sperm pronuclear formation in vitro. The cytoplasmic preparation was separated into soluble and particulate fractions by centrifugation and then each fraction was injected into enucleated eggs to determine whether or not it restored the ability to decondense sperm nuclei. We found that the soluble, but not the particulate fraction could restore the ability to decondense sperm nuclei to enucleated oocytes. This result clearly indicates that the soluble fraction contains most of the GV material required for chromatin decondensation. However, since the soluble fraction fails to decondense sperm chromatin in vitro in the absence of material from the paticulate fraction, sperm pronuclear formation appears to require both the soluble material derived from the GV and particulate material which can develop in the oocyte cytoplasm in the absence of the GV. | ||

abstract |
The chromatin of Xenopus laevis sperm nuclei was induced to decondense, swell and form mitotic chromosomes following its injection into mature Rana pipiens oocytes. In contrast, the sperm chromatin did not decondense or form mitotic chromosomes when injected into oocytes from which the germinal vesicle (GV) was removed prior to the initiation of maturation. Injection into enucleated oocytes of the material extracted from manually-isolated GVs restored their ability to decondense sperm nuclei. This soluble GV material was stable at 18 ^oC for 16 h but was inactivated by heating to 80 ^oC for 10 min. We examined the distribution of this GV material in a cytoplasmic preparation from activated eggs which can induce sperm pronuclear formation in vitro. The cytoplasmic preparation was separated into soluble and particulate fractions by centrifugation and then each fraction was injected into enucleated eggs to determine whether or not it restored the ability to decondense sperm nuclei. We found that the soluble, but not the particulate fraction could restore the ability to decondense sperm nuclei to enucleated oocytes. This result clearly indicates that the soluble fraction contains most of the GV material required for chromatin decondensation. However, since the soluble fraction fails to decondense sperm chromatin in vitro in the absence of material from the paticulate fraction, sperm pronuclear formation appears to require both the soluble material derived from the GV and particulate material which can develop in the oocyte cytoplasm in the absence of the GV. |

In contrast, the sperm chromatin did not decondense or form mitotic chromosomes when injected into oocytes from which the germinal vesicle (GV) was removed prior to the initiation of maturation. Injection into enucleated oocytes of the material extracted from manually-isolated GVs restored their ability to decondense sperm nuclei. This soluble GV material was stable at 18 ^oC for 16 h but was inactivated by heating to 80 ^oC for 10 min. We examined the distribution of this GV material in a cytoplasmic preparation from activated eggs which can induce sperm pronuclear formation in vitro. The cytoplasmic preparation was separated into soluble and particulate fractions by centrifugation and then each fraction was injected into enucleated eggs to determine whether or not it restored the ability to decondense sperm nuclei. We found that the soluble, but not the particulate fraction could restore the ability to decondense sperm nuclei to enucleated oocytes. This result clearly indicates that the soluble fraction contains most of the GV material required for chromatin decondensation. However, since the soluble fraction fails to decondense sperm chromatin in vitro in the absence of material from the paticulate fraction, sperm pronuclear formation appears to require both the soluble material derived from the GV and particulate material which can develop in the oocyte cytoplasm in the absence of the GV.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lohka, M.J.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Masui, Y.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Experimental Cell Research</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">148(1983), 2, Seite 481-491</subfield><subfield code="w">(DE-627)NLEJ177031808</subfield><subfield code="w">(DE-600)1466780-0</subfield><subfield code="x">0014-4827</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:148</subfield><subfield code="g">year:1983</subfield><subfield code="g">number:2</subfield><subfield code="g">pages:481-491</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1016/0014-4827(83)90169-6</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">148</subfield><subfield code="j">1983</subfield><subfield code="e">2</subfield><subfield code="h">481-491</subfield></datafield></record></collection>
