Answer:
The cells responsible for the healing process of a wound, such as Xavier's cut, are primarily **fibroblasts**. These cells play a crucial role in wound healing by producing collagen and extracellular matrix, which are essential for the repair and formation of new tissue.
Other important cells involved in the wound healing process include:
1. Platelets: They help in blood clotting and release growth factors that initiate the healing process.
2. Neutrophils: These are a type of white blood cell that helps to clean the wound by removing debris and fighting infection.
3. Macrophages: They also help in cleaning the wound and release cytokines that promote tissue regeneration.
4. Keratinocytes: These cells help in re-epithelialization, which is the process of forming new skin over the wound.
5. Endothelial Cells: They are involved in forming new blood vessels to supply nutrients and oxygen to the healing tissue.
Together, these cells coordinate to stop bleeding, fight infection, form new tissue, and ultimately heal the wound.
