Histological and Morphological Characterization of Developing Dermal Lymphatic Vessels

Area of Science:

• Developmental Biology
• Vascular Biology
• Immunohistochemistry

Background:

• Three-dimensional visualization of lymphatic vasculature has significantly advanced understanding of developmental morphogenetic mechanisms.
• Assessing gene and signaling pathway functions in dermal lymphatic vasculature development typically involves two complementary approaches.

Purpose of the Study:

• To present detailed protocols for multicolor immunofluorescent immunostaining of embryonic mouse dorsal skin and thin tissue cryosections.
• To enable high-resolution imaging of dermal lymphatic vasculature for in-depth characterization of developmental phenotypes.

Main Methods:

• Whole-mount immunostaining of embryonic mouse skin for 2D and 3D analysis of lymphatic vessel network patterning and morphology.
• Immunostaining of thin tissue sections to examine lymphatic vessel identity, lumen formation, and protein localization in endothelial cells.

Main Results:

• Detailed protocols for multicolor immunofluorescent staining of embryonic dorsal skin and cryosections are provided.
• These methods generate high-resolution images of the dermal lymphatic vasculature.

Conclusions:

• The presented protocols are integral for in-depth characterization of lymphatic vessel phenotypes in the developing mouse embryo.
• These techniques facilitate the study of genes and signaling pathways crucial for lymphatic vascular development.
