SYSTEMS, METHODS, AND CELLULAR COMPOSITIONS THEREOF, INVOLVING INTRODUCTION, ATTACHMENT AND PROLIFERATION OF TROPHECTODERM CELLS IN A BLASTOCYST

摘要

A method of improving quality of a blastocyst is described. The method includes removing a segment of trophectoderm from a first blastocyst. The method also includes removing a portion of trophectoderm from a second blastocyst. In addition, the method includes introducing to the second blastocyst the segment of trophectoderm from the first blastocyst. The method will promote attachment and proliferation of the trophectoderm in the second blastocyst. The first and second blastocyst will often be obtained from a same or similar period of time after insemination. The first blastocyst will have a same quality or better quality trophectoderm than the second blastocyst. The second blastocyst will include the segment of trophectoderm from the first blastocyst.
