Biology on Instagram: "Regeneration ability 🪱 Planarians have a remarkable ability to regenerate, capable of regrowing entire bodies from small fragments. This is due to a large population of stem cells called neoblasts, which can become any cell type, and a genetic blueprint for body organization. When injured, neoblasts are activated to form a blastema, a mass of new cells that differentiate to replace the missing tissues, such as a head or tail. 🎥 by fishyscience (yt) #regener
