Which of the following CANNOT be formed from culturing mesenchymal tissue?
Show answer and explanation
Correct answer: A. Mucosa (epithelial component)
- A. Correct. MUCOSA (specifically its EPITHELIAL component) CANNOT form from mesenchyme. Epithelium is derived from ECTODERM or ENDODERM — not mesoderm/mesenchyme. Oral mucosa has epithelium (ectodermal origin) supported by lamina propria connective tissue (mesenchymal origin). Mesenchyme produces: connective tissue, bone, cartilage, muscle, blood — NOT epithelium.
- B. Incorrect — bone CAN form from mesenchyme. Osteoblasts and bone are derived from mesenchymal stem cells.
- C. Incorrect — connective tissue CAN form from mesenchyme. Fibroblasts are quintessential mesenchymal cells.
- D. Incorrect — cartilage CAN form from mesenchyme. Chondroblasts are mesenchymal derivatives.
