Article Snippet: To examine whether our IPF-Fib with iAT2 I73T/tdT cell co-culture organoid model will respond to the FDA approved therapy Nintedanib (Medchem Express, cat. BIBF 1120) and the TGFβ inhibitor SB-431542 (Alk5 inhibitor) (Medchem Express, cat. HY-10431), we tested these drugs in the organoid co-cultures using fibroblasts derived from two individual IPF patients in combination with the iAT2 I73T/tdT cells.
