Collagen inside cells is liquid-like, not rigid

biology

New research shows collagen, the human body's most abundant protein, isn't the rigid structural protein we've always assumed. Inside cells, it behaves like a liquid, which completely contradicts textbook descriptions. The study's specifics aren't detailed here, but the shift in understanding is significant. This is one of those findings that makes you wonder how many other 'textbook certainties' are actually fluid—or at least, fluid under certain conditions. If collagen can switch states depending on location, what does that mean for how we model cellular mechanics? The implications aren't just academic; they could reshape how we think about tissue formation, disease mechanisms, or even drug delivery.
