A method for semi-automatic grading of human blastocyst microscope images. by Santos Filho, E, Noble, J, Poli, M, Griffiths, T, Emerson, G, Wells, D

“…The value 0.92 was the highest accuracy achieved in the tests with 73 blastocysts. CONCLUSIONS: Semi-automatic grading of human blastocysts by a computer is feasible and may offer a more precise comparison of embryos, reducing subjectivity and allowing embryos with apparently identical morphological scores to be distinguished.…”

Transcriptomic difference in bovine blastocysts following vitrification and slow freezing at morula stage. by Alisha Gupta, Jaswant Singh, Isabelle Dufort, Claude Robert, Fernanda Caminha Faustino Dias, Muhammad Anzar

“…Bovine compact morulae were vitrified or slow-frozen, and post-warm morulae were cultured to the expanded blastocyst stage. Blastocysts developed from vitrified and slow-frozen morulae were subjected to microarray analysis and compared with blastocysts developed from unfrozen control morulae for differential gene expression. …”
