Genetically-modified hiPSCs expressing the genetically-encoded calcium indicator jRCaMP1b with a nuclear export signal (NES). This reporter is used to track calcium dynamics in live cells. It combines a red fluorescent protein with calmodulin and a calcium-binding domain, changing fluorescence intensity upon calcium binding. Its red-shifted emission is ideal for imaging in complex tissues or dual-color experiments, making it valuable for studying calcium-mediated processes.
A single copy of this reporter was integrated using the STRAIGHT-IN platform at the AAVS1 locus. See below!

Tell me if I should add you but try to make sure, that you're not already in Part 1.
I cannot cross-reference everyone ๐Ÿ˜…

Cyan cellular extracellular matrix fibers are highlighted laying over the top of the orange hyaluronan secreted matrix after a scratch would assay.

Dedicating this #Fluorescencefriday to the #ECMatrix lovers. Was trialing some ECM staining methods on a scratch wound and love the HABP staining looking almost like flames ๐Ÿ”ฅ๐Ÿงช๐Ÿ”ฌ
