Isolation of Human Lymphatic Endothelial Cells by Multi-parameter Fluorescence-activated Cell Sorting
Published on: May 1, 2015
Summary
The fibrous capsule separates tissue fluid pools, creating distinct lymph and edema types. This research identifies intracapsular pitting edema and extracapsular non-pitting edema based on fluid dynamics.
Area of Science:
- Physiology
- Edema Pathophysiology
Background:
- The interstitial fluid environment is compartmentalized by fibrous capsules surrounding tissue modules.
- Understanding fluid dynamics within these compartments is crucial for differentiating edema types.
Purpose of the Study:
- To elucidate the role of the fibrous capsule in interstitial fluid compartmentalization.
- To differentiate between intracapsular and extracapsular edema based on fluid origin and lymphatic drainage.
Main Methods:
- Analysis of fluid dynamics within tissue modules and surrounding clefts.
- Investigation of the permeability of the capsular barrier.
- Experimental differentiation of edema types based on pitting and non-pitting characteristics.
Main Results:
- The fibrous capsule divides interstitial fluids into intracapsular and extracapsular pools.
- Extracapsular fluid filtering into clefts forms the source of lymph.
- Lymph composition differs from capillary ultrafiltrate due to capsular barrier permeability.
- Two distinct edema types were identified: intracapsular pitting and extracapsular non-pitting edema.
Conclusions:
- The fibrous capsule plays a critical role in regulating interstitial fluid composition and volume.
- Lymphatic drainage systems manage extracapsular fluids.
- This compartmentalization model explains the distinct characteristics of pitting and non-pitting edema.

01:20Fluid Connective Tissues: Blood and Lymph
Blood and lymph are fluid connective tissues. They contain cells, also known as formed elements, circulating in a liquid extracellular matrix, the plasma. The formed elements are derived from hematopoietic stem cells in the bone marrow. Blood and lymph connect all vital parts and carry nutrients, oxygen, and other essential molecules like antibodies.
Blood
The blood flows through blood vessels— arteries, capillaries, and veins. Blood plasma is primarily made of proteins, solutes, and water.

01:23Introduction to Lymphatic and Immune System
Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are born...

01:28Functions of the Lymphatic and Immune System
The lymphatic system plays a crucial role in bolstering our immune system. It consists of a network of lymphoid organs, lymph, and lymphatic vessels that provide structural and functional support in safeguarding the body against pathogens such as viruses and bacteria.
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...

01:16Lymphatic Vessels and Lymph Transport
Lymphatic vessels, known as lymphatics, are crucial in transporting lymph from peripheral tissues to our venous system. This process begins with lymph entering through tiny capillaries that branch through tissues. These capillaries have unique features such as larger diameters, thinner walls, and a distinctive one-way valve system formed by overlapping endothelial cells.
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular spaces.

01:23Detailed Structure and Function of Lymph Nodes
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

01:15Development of the Lymphatic System
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
