Single cell RNA sequencing of healthy and trisomy 21 (Down's syndrome) foetal liver and foetal bone marrow
Here, we performed single cell RNA sequencing (scRNA-seq) of human fetal liver and bone marrow tissue samples from 15 trisomy 21 (Ts21) and 3 healthy foetuses (median age 14 post-conception weeks). The data set is composed of approximately 1.1 million cells from three different populations: CD235- (niche and haematopoietic cells depleted of erythrocytes), CD34+/Lin- (haematopoietic progenitors), and CD45+ (all haematopoietic cells).
