With all that science knows about the human body, it is truly amazing that they have just made a new human organ discovery. Scientists at the New York University Langone School of Medicine have announced the discovery of a previously unknown organ in the human body. They gave it the name “interstitium.”
The human body is about 60% water, most of which is in the cells. The interstitium is a network of fluid-filled spaces, and it holds about 20% of all the fluid in the human body. The reason this organ wasn’t detected earlier is that researchers treat and dehydrate the tissue samples before they put them under a microscope. That causes the interstitium to collapse. Until now researchers saw the interstitium as a dense wall of the protein collagen. They now realize that it is not a wall but an “open, fluid-filled highway” supported by a lattice of collagen.
The interstitium organ plays a major role in the immune system. Interstitial fluid is the source of lymph, which sends out white blood cells to fight infection. The interstitium’s role in the body’s battle against infection is significant, and this discovery may change how some difficult infections are treated.
Medical researchers discovered the interstitium by using a new imaging technique called probe-based confocal laser endomicroscopy (pCLE) to examine living tissue. They found interstitium tissue under the surface of the skin, in the lining of the digestive tract and lungs, and surrounding the muscles. This new human organ discovery helps explain how cancer cells spread throughout the body.
We still have much to learn about the design and function of our bodies, but we see God’s wisdom and the complexity of His creation as we grow in our understanding of how our bodies work. David said it best in Psalms 139:14, “I am fearfully and wonderfully made, marvelous are your works God, and my soul knows that very well.”
