举一反三
- In the thymus, thymic stromal cells(TSCs) are interconnected into a network structure. These cells carry a large number of surface molecules and can secrete a variety of thymic hormones and cytokines, which provides a suitable microenvironment for the development and maturation of thymocytes. The types of TSCs include ( ). A: epithelial cell B: macrophage C: dendritic cell D: neutrophil
- In the following cells, which cell is derived from monocytes A: fibroblast B: macrophage C: mast cell D: plasma cell E: fat cell
- Which of the following cells can not be found in the skin? A: Merkel cell B: Kupffer cell C: Langerhans cell D: Melanocyte
- Which<br/>of the following cells are found in the epidermis?() A: Keratinocyte B: Melanocyte C: Merkel’cell D: Adipocyte E: Langerhans’s cell
- Which<br/>of the following cell is not labile cell () A: urothelial<br/>cell B: epidermis C: Lymphohematopoietic<br/>cell D: hepatocyte E: respiratory<br/>epithelial cell
