Dissociation of Placental Tissues for Single-Cell Techniques

Abstract

The dissociation of whole tissue into single-cell suspensions is a critical step for techniques focused on profiling of individual cells. Here, we describe a protocol for the preparation of high-quality single-cell suspensions from human placental tissues: the basal plate (BP), placental villi (PV), and chorioamniotic membranes (CAM). This protocol also provides guidance for the cryopreservation and recovery of single-cell suspensions for later use. The methods described here have been demonstrated to be suitable for downstream single-cell applications, such as single-cell RNA-sequencing, that require viable, high-quality cell suspensions.
