Definitions

  • oocytes With techniques being developed for _in vitro fertilization as well as the more recent nuclear trans ⁇ fer techniques in bovine embryos, a source of readily available oocytes would compliment the procedures available for genetic selection and breeding. Immature ova have been collected from bovine ovaries at abba- toirs, and the follicles were aspirated to release cumulus-oocyte complexes. The oocytes have been tested for maturation in media containing hormones and granu- losa cells. The interaction of granulosa cells with cumulus complexes have been determined to contribute to developmental competence of bovine oocytes.
  • Activation is the term used for the initiation of the developmental program which normally occurs at the time of fertiliza ⁇ tion. Activation can be induced by electropulsation without fertilization of the oocyte. Control over activation is important in nuclear transfer to optimize the time to implant the transferred nuclear material which incorporates into and "reconditions" in the presence of recipient maturing ooplasms.
  • the subsequent development is intended to reflect the genetic make-up of the transferred nuclear material after insertion into an enucleated egg.
  • a suitable supply of immature bovine oocytes exists and is inexpensive.
  • a reliable in vitro maturation procedure would give synchronous and measurable oocyte development. Therefore, a mature supply of oocytes would be available for use for genetic selective breeding or cloning.
  • the present invention is a new method for _in vitro maturation of bovine oocytes.
  • the process can be used to produce oocytes for nuclear transfer, and pregnancies have been confirmed.
  • bovine oocyte _in vitro maturation with the co-culture feature is successful for use in the nuclear transfer process to produce cloned animals.
  • the use of unique recombinant gonadotropins is another feature of the new process to mature the bovine oocytes.
  • the bovine ovaries were collected at abattoirs and maintained and transported in Dulbeccos PBS at 32° to 39°C. The collection and transport time ranged from 1.5 to 3.75 hours past death.
  • the compact cumulus oocyte complexes (COC) were selected from the aspirate of antral follicles. Some follicles were dissected as discussed below.
  • the follicle size was investigated as to the best source of oocytes. The most useful range is 3-8 mm. The preferred follicle size determined to give the best oocytes for further developmental competence were 6-8mm. Although the l-2mm follicles yielded some oocyctes that would mature to develop to morula and blastocyst stage after in vitro fertilization, the development was at a lower frequency. The follicle size was examined in dissected ovaries because 2mm and 3-5mm follicles are difficult to distinguish when measured at the ovarian surface.
