Synovial Biopsy, Synovium, Synovial Fluid & Arthrocentesis
About H. Ralph Schumacher, Jr., M.D.
H. Ralph Schumacher, Jr., MD is Professor of Medicine at the University of Pennsylvania School of Medicine, Director of the Arthritis-Immunology Center at the Philadelphia VA, and former Chief of Rheumatology at the VA Medical Center, Philadelphia. He has been studying all aspects of the synovium, synovial fluid and crystal deposition disease for 40 years. He is preparing this resource to make his educational material widely accessible and to encourage dialogues on these subjects. He is author of scientific papers, books, and many reviews and editorials. His work has addressed clinical aspects, light and electron microscopy, immunohistochemistry, molecular biology and physiology of the joint.

Some Life Lessons that I See Suggested from My Electron Micrographs:
This synovial macrophage is reaching out with dramatic processes to enfold a lymphocyte. EM, 7500X..
Platelets sticking together are occluding synovial vessel. Multilaminated basement membrane seems to suggest a wrapping. EM, 5000X.
Activated lymphocytes and adjacent plasma cell with rough endoplasmic reticulum cooperate in stimulation and antibody production. EM, 25,000X..
DEPART FROM THE ROUTINE
Very unusual pericyte processes depart from the routine and extend through venule endothelial gaps, EM, 10,000X..
Multiple "arms" from this synovial cell enfold a process from another cell. EM, 30,000 X.
This intraluminal leukocyte is degranulating in a vessel wall injured by dense deposits of presumed immune complexes, EM, 6,000X.
The large cell with profuse polyribosomes is a lymphoblast transformed from a small lymphocyte. EM, 20,000X.
TRY TO HEAL
A vessel has been destroyed and is beginning to be replaced by a fibrous scar. EM, 6,000 X.
BE A BIT MYSTERIOUS AND NOT AFRAID TO BE PUZZLED
What is going on in this cell? EM, 28,000 X.
This mast cell produces histamine and other vasoactive substances to act on the adjacent vessel. EM, 10,000 X.
