Outline of Final Research Achievements

Mast cells are derived from hematopoietic stem cells, and are migrate into peripheral tissues as immature progenitor, and are differentiate into mature mast cells with various phenotypes depending on the microenvironment. As mast cells play central roles in allergy responses, it is important for development of therapies and drugs to understand the characters and properties of in vivo mature mast cells in each peripheral tissues. However, their characters and properties remains uncertain, because they are sparsely existed in the peripheral tissues. Then, I established a RNA amplification method for a transcriptome analysis of single mast cell. The yield of amplified RNA was sufficient for the single-cell transcriptome analysis and amplified RNA reflected aspects between mast cells with the distinct properties.
