Which of the following CANNOT be formed from mesenchymal tissue culture?

Mucosa
Skeletal muscle
Bone
Cartilage

Show answer and explanation

Correct answer: A. Mucosa

Mesenchymal stem cells can differentiate into bone (osteoblasts), cartilage (chondrocytes), muscle (myocytes), adipose tissue, and connective tissue. Mucosa (epithelium) is derived from ECTODERM, not mesenchyme. Therefore, mucosa is the EXCEPTION — it cannot be cultured from mesenchymal tissue.
