All of the following can be formed from culturing mesenchymal tissue EXCEPT:

  1. Skeletal muscle
  2. Bone
  3. Cartilage
  4. Mucosa (epithelium)
Show answer and explanation

Correct answer: D. Mucosa (epithelium)

  • A. ❌ — mesenchyme CAN form this. Skeletal muscle is derived from mesodermal/mesenchymal progenitors.
  • B. ❌ — mesenchyme CAN form this. Bone is formed by osteoblasts from mesenchymal progenitors.
  • C. ❌ — mesenchyme CAN form this. Cartilage is a connective tissue from mesenchymal cells.
  • D. ✅ Correct. — this is the EXCEPTION. Mucosa/epithelium is derived from ectoderm, NOT mesenchyme. Mesenchymal stem cells differentiate into bone, cartilage, fat, and muscle — but NOT epithelial structures.
