Research Interests

Cellular and molecular basis of hematopoietic stem cell and tissue-resident macrophage development; the roles of microglia and Langerhans cells in organ development and tissue regeneration.

Wen’s laboratory is keen to understand the developmental mechanism that establishes the cellular components of the blood system and how their dysregulation incurs diseases by utilizing zebrafish (Danio rerio), a tiny tropical fish whose blood system shares many similarities to human. A combination of photo-inducible lineage tracing, time-lapse imaging and devising genetic strategies will be employed to investigate the origin, migration and colonization, fate determination and function of hematopoietic stem cells, microglia and Langerhans cells in the intact developing and adult zebrafish with highest possible cellular resolution. The ultimately goal is to uncover novel cellular and molecular principles that organize the formation, maintenance and function of these hematopoietic cells under physiological and pathological states.
