Researchers at CAS Guangzhou Institute of Biomedicine and Health grow human teeth-like structures from iPS cells

Directed by Dr PEI Duanqing, the iPS cells were isolated from human urine and expanded with dental mesenchymal cells isolated from mouse embryos. After 3 weeks, tooth like structures including dental enamel, dentin, dental pulp and cementum were formed though not adequate yet in view of hardness.

BGI and allied hospital announce first preimplantation whole genome sequencing on IVF baby

On August 24, 2012, the world’s first IVF baby sequenced before implantation was born in Hunan Province, China. Five days after fertilization in vitro, 7 embryos were biopsied and all samples were shipped to BGI for preimplantation sequencing. Based on a combination of next-generation sequencing and bioinformatics analysis, 3 embryos were found to have normal chromosomal content and two of them were selected for transfer resulting in pregnancy. The baby is now 11 months old, healthy and developing normally. BGI press release, July 22, 2013
