Abstract
The placenta is a heterogeneous and complex organ with multiple cell types, posing a challenge for the field of maternal-fetal medicine to implement single-cell technologies for a deeper characterization of this essential organ. Several protocols use enzymes to digest the tissue and generate single cell suspension, but this approach has several shortcomings including the loss and reduced viability of cells. In this study, we describe a non-enzymatic approach to generate single cell suspension from placental tissue with high yield and viability for single cell RNA sequencing.

10m 30s
Transform placenta sections into gentle MACs C-tube containing Amount3000 µL of MACs running buffer.
Pipetting
Set up a gentle MACS dissociator program to h-cord-01 for 553 rotation per round (rpr) at Duration00:00:30 .

30s
After the run, centrifuge at Centrifigation300 x g for Duration00:10:00 at Temperature40 °C .

10m
Centrifigation
Remove the supernatant leaving Amount200 µL to resuspend pellet in. Transfer pipettes may be used to remove supernatant after centrifugation to minimize loss of placenta cells.

Pipetting
Amount10 µL of placental cells can be counted on a countess II cell counter or using trypan blue.
