To achieve the full potential of stem cells in regenerative medicine and disease modeling, high conversion efficiency from hESCs/hiPSCs to neural cells is crucial. A supplement of this small molecule cocktail in cell culture media simplifies the process and increases the productivity of neural and neuronal cell generation.

Repro-nLS (also named as LSB in reference 1) is a combination of two small-molecule inhibitors (LDN193189 and SB431542). Under the Repro-nLS condition, both BMP (ALK2/3) and TGF-beta 1(ALK4/5/7) signaling pathways are inhibited by LDN193189 and SB431542 respectively. hESCs/hiPSCs can be efficiently converted into neural precursor cells in a monolayer fashion under this dual SMAD inhibition. More than 80% of hESCs are rapidly and uniformly converted into Pax6+ neural precursor cells. This cocktail can be further combined with other patterning factors to readily generate subtype specific neural and neuronal cells ^1-3, such as nociceptors when used with 3i ¹ (SU5402, CHIR99021 and DAPT)( See Repro-nLSB3i).
