A Technique to Generate a 2D Monolayer of Cerebellar Cells from Induced Pluripotent Stem Cells

Abstract

This video demonstrates a protocol for differentiating human induced pluripotent stem cells into cerebellar progenitors. It involves transferring stem cell colonies to an ultra-low attachment plate to form embryoid bodies, promoting differentiation with growth factors, and then transferring the embryoid bodies onto a matrix-coated plate for adhesion. Subsequent steps involve inducing cell migration and adding a maturation medium to guide the development of glutamatergic and GABAergic cerebellar neuronal precursors and Purkinje cell progenitors.

Protocol

1. Experimental preparation

1. Prepare basement membrane matrix (BMM)-coated plates.
   NOTE: BMM solidifies more quickly at warmer temperatures. Plates must be prepared rapidly and immediately placed at 4 °C for storage.
   1. Thaw the BMM (see Table of Materials) on ice, at 4 °C for at least 2 h, or overnight.
   2. Mix Dulbecco's Modified Eagle Medium (DMEM)/F12 and BMM to a final concentration of 80 µg/mL. Distribute the BMM solution in tissue culture dishes (1 mL for 35 mm and 2 mL for 60 mm dishes) and incubate at 37 °C for at least 1 h or overnight before plating the....
