The mitochondrial respiration signature of the bovine blastocyst reflects both environmental conditions of development as well as embryo quality by Jessica Kurzella, Dennis Miskel, Franca Rings, Ernst Tholen, Dawit Tesfaye, Karl Schellander, Dessie Salilew-Wondim, Eva Held-Hoelker, Christine Große-Brinkhaus, Michael Hoelker

“…This was achieved by taking advantage of two generally accepted metrics for developmental capacity: (I) environmental conditions during development (vivo vs. vitro) and (II) developmental kinetics (day 7 vs. day 8 blastocysts). Our study showed that the developmental environment affected total embryo oxygen consumption while different morphokinetics illustrating the embryo qualities correlate with maximal mitochondrial respiration, mitochondrial spare capacity, ATP-linked respiration as well as efficiency of ATP generation. …”

The morphokinetic signature of human blastocysts with mosaicism and the clinical outcomes following transfer of embryos with low-level mosaicism by Yaoyu Zou, Yilun Sui, Jing Fu, Naidong Ge, Xiaoxi Sun, Yijuan Sun

“…Abstract Background Genetic mosaicism is commonly observed in human blastocysts. Embryos’ morphokinetic feature observed from time-lapse monitoring (TLM) is helpful to predict the embryos’ ploidy status in a non-invasive way. …”
