Isolation of Human Lymphatic Endothelial Cells by Multi-parameter Fluorescence-activated Cell Sorting
Published on: May 1, 2015
Summary
Plasma protein concentration in implanted capsules and lymphatic fluid are similar after one month. Early implantation shows higher protein in capsules, likely due to inflammation and sampling delays, but lymphatic vessels reflect tissue fluid protein levels.
Area of Science:
- Biomedical Engineering
- Physiology
- Fluid Dynamics
Background:
- Understanding plasma protein concentration in tissue fluid is crucial for studying lymphatic function.
- Implanted capsules provide a model to investigate fluid dynamics and protein transport in subcutaneous tissues.
Purpose of the Study:
- To compare plasma protein concentrations in fluid from implanted capsules and surrounding lymphatic vessels.
- To determine the influence of implantation time and local inflammation on protein levels.
- To model the concentrating ability of initial lymphatics.
Main Methods:
- Analysis of plasma proteins in fluid from implanted capsules and adjacent small lymphatic vessels.
- Comparison of protein concentrations based on capsule implantation duration (less than one month vs. greater than one month).
- Development of a mathematical model for initial lymphatic concentrating mechanisms.
Main Results:
- Capsular and lymphatic fluid protein concentrations were statistically similar for implants older than one month.
- Capsules implanted for less than one month showed significantly higher total protein than lymphatic fluid.
- A model suggests initial lymphatics' concentrating ability depends on leaked fluid fate and surrounding fluid dynamics.
Conclusions:
- Lymphatic vessels, particularly in subcutaneous regions, generally reflect the plasma protein concentration of surrounding tissue fluids.
- Early implantation times and local inflammation can temporarily elevate protein levels in capsular fluid.
- The study highlights the dynamic nature of fluid and protein exchange in the interstitial space and lymphatic system.

01:20Overview of the Vascular System
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...
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.

01:15Development 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...
