Cells have tendrils!
My mental image of cells is of balloons, stacked, drifting or bumping but always discrete. Now it seems it’s a shifting tendril jungle at the bottom. Staggering!
[In] one of the biggest discoveries in biology of recent times.. using video microscopy [!], they watched adjacent cells reach out to each other with antenna-like projections, establish contact and then build the tubular connections. The connections were not just between pairs of cells. Cells can send out several nanotubes, forming an intricate and transient network of linked cells lasting anything from minutes to hours.
