GSE121179: Next generation seuquencing of 3D breast cancer cell culture in synthetic hydrogels presenting either a collagen mimic or laminin mimic

• Organsim human
• Type RNASEQ
• Target gene
• Project ARCHS4

MDA-MB-231 (ER-) and T47D (ER+) breast cancer cells were encapsulated in synthetic hydrogels, formed with a multi-arm bioinert polymer poly(ethylene glycol), cell-degradable peptide crosslinks, and receptor-binding pendant peptides, and cultured for 3 days to assess initial cell responses to different matrix compositions. The synthetic matrices had a Young's modulus (E) ~ 0.6 kPa, in the range of bone marrow and healthy mammary tissue, and biochemcial cues to mimic binding sites found in collagen (GFOGER peptide) or laminin (IKVAV peptide). After 3 days in culture, mRNA was collected and RNA-seq performed to compare cell responses between the collagen and laminin mimetic cultures.
