The cell membrane modification of red blood cells (RBCs) with hyperbranched polyglycerol (HPG) is presented. Modified RBCs were characterized by aqueous two phase partitioning, osmotic fragility and complement mediated lysis. The camouflage of surface proteins and antigens was evaluated using the flow cytometry and Micro Typing System (MTS) blood phenotyping cards.

Pancreatic Islets Isolation through Collagenase Perfusion: An Enzymatic Method to Isolate Pancreatic Islet Cells
0 Views •
2023
Pancreatic islets, also called the Islets of Langerhans, are a cluster of endocrine cells which produces hormones for glucose regulation and other important biological functions. This protocol explains a method for isolating pancreatic islets by first perfusing collagenase via Ampulla of Vater to digest the exocrine pancreatic tissue and a simplified density gradient centrifugation to purify the islets from mice.
FAQs
Inflammation, oxidative stress, duct obstruction, metabolic strain, and repeated cellular injury can progressively reduce the pool of viable pancreatic cells. Damage to acinar cells threatens digestive enzyme secretion, while injury to islet cells can impair insulin production. Addressing these pathways matters because continued cellular loss may compromise both digestive activity and glucose regulation.
Acinar and islet cells support different but complementary pancreatic roles. Acinar cells contribute to exocrine digestion through enzyme secretion, whereas islet cells support endocrine control through insulin production. Protective strategies therefore aim to limit injury across both cell populations, rather than focusing on glucose regulation or digestion alone.
The approach considers two functional outcomes at once: maintaining insulin production for glucose regulation and preserving digestive enzyme secretion. This distinction helps explain why pancreatic disease can create different or combined complications. A strategy that preserves one role may not fully preserve the other, so protection is relevant to the gland’s overall functional capacity.
Protection becomes especially relevant when pancreatic tissue faces pancreatitis, diabetes, pancreatic disease, or the stress associated with pancreatic surgery. These settings may threaten endocrine activity, exocrine activity, or both. Limiting additional injury can help preserve remaining function and may support decisions about treatment and long-term management.
The central logic is to identify and reduce factors that injure pancreatic tissue while preserving cells that remain viable. In practice, this frames protection as limiting ongoing inflammation, oxidative stress, duct obstruction, metabolic strain, and repeated injury. The intended outcome is retention of pancreatic capacity rather than waiting for progressive failure before acting.
After pancreatic surgery, the amount of functioning tissue may be especially important for maintaining insulin production and digestive enzyme secretion. Protection in this context supports attention to the function that remains after the procedure. Preserving that capacity can reduce complications and help guide subsequent treatment decisions.
Useful outcomes include maintaining glucose regulation, sustaining digestion, reducing complications, and limiting progression toward pancreatic failure. These outcomes reflect the pancreas’s endocrine and exocrine roles rather than a single laboratory measure. Evaluating them can help determine whether a protective strategy preserves meaningful function in people with pancreatic disease.
The concept provides a framework for developing therapies that prevent progressive pancreatic failure. Research can examine whether interventions reduce inflammation, oxidative stress, obstruction, metabolic strain, or repeated cellular injury while retaining viable acinar and islet cells. This connects cellular preservation with clinically relevant goals such as maintaining digestion and glucose regulation.
