Semen quality and fertility effectiveness of cloned buffalo (Bubalus bubalis) bulls
Revista CientÃfica, 2023 In India, due to a severe shortage of elite bulls, semen available from progeny-tested bulls covers a limited breedable population of buffalo. Animal cloning has proved beneficial in making identical genetic copies in the shortest possible time to meet ...

Endometrial stromal cells of women with recurrent miscarriage fail to discriminate between high- and low-quality human embryos [PDF]
, 2012 Background The aetiology of recurrent miscarriage (RM) remains largely unexplained. Women with RM have a shorter time to pregnancy interval than normally fertile women, which may be due to more frequent implantation of non-viable embryos.

IGF1-mediated human embryonic stem cell self-renewal recapitulates the embryonic niche
Nature Communications, 2020 The signals regulating the establishment and maintenance of the pluripotent epiblast in human embryos are unclear. Here, the authors use a bioinformatics approach to identify the role of IGF1 in human embryo development, and from this, propose a culture ...
