Human Embryonic Lymphatic Progenitor Cell Origin and Early Lymphangiogenesis
During human embryogenesis, lymphatic progenitor cells emerge primarily from mesodermal tissues, with paraxial mesoderm serving as the principal source. By approximately week 6-7 of human gestation (equivalent to E12.5 in the comparative mouse model shown in the right side of the image), a significant milestone in lymphatic development occurs as initial lymphatic endothelial cells (LECs) begin sprouting from the cardinal vein and organizing into primitive lymphatic structures.
Embryonic Lymphatic System Development: Molecular Regulation of Lymphangiogenesis
The development of the lymphatic vascular system represents a fascinating and complex process that occurs during embryogenesis. Beginning around embryonic day 9.5 (E9.5) in mice and approximately week 6-7 in human embryos, lymphatic endothelial cell (LEC) progenitors emerge from the cardinal vein through a tightly regulated molecular cascade. This process, known as lymphangiogenesis, is orchestrated by key transcription factors, growth factors, and signaling pathways that ensure proper lymphatic vessel formation.
The Plexus of Raschkow: Neural Network of the Dental Pulp Explained
This histological image clearly demonstrates this specialized nerve network located primarily within the cell-free zone of Weil, just beneath the odontoblast layer of the dental pulp. The plexus consists of densely packed unmyelinated nerve fibers that form an intricate meshwork before sending terminal branches toward the odontoblast layer and into dentinal tubules. This arrangement facilitates the tooth's sensory function, allowing it to respond to various stimuli including temperature changes, mechanical pressure, and chemical irritants.
Dental pulp of a stained and decalcified tooth
This histological image showcases a decalcified and stained tooth section, providing an excellent visualization of the dental pulp's anatomical organization. The preparation technique has removed the mineral content of the hard dental tissues while preserving the soft tissue architecture, allowing for clear identification of the two primary anatomical divisions of the dental pulp: the coronal pulp chamber and the radicular pulp within the root canals.
Diagram showing pulp histology
This histological image provides an excellent visualization of the four distinct histological zones that comprise healthy dental pulp tissue. The left side of the image shows a low-magnification view of a tooth section with pulp tissue highlighted, while the right side presents a higher-magnification view clearly delineating the four specialized zones: the odontoblast layer, the cell-free zone of Weil, the cell-rich zone, and the central pulp core.
