Abstract

Insights

Bone marrow microvesicles derived from mesenchymal stem cells protect against acute pancreatitis. These microvesicles reduce inflammation and improve pancreatic cell survival, offering a potential treatment for severe acute pancreatitis.

Area of Science:

  • Regenerative Medicine
  • Cell Biology
  • Gastroenterology

Background:

  • Mesenchymal stem cells (MSCs) demonstrate protective effects in acute pancreatitis (AP).
  • Investigating cell-free therapeutic approaches using MSC-derived products is crucial for AP treatment.
  • Microvesicles (MVs) are emerging as key mediators of MSC therapeutic potential.

Purpose of the Study:

  • To evaluate the therapeutic effect of bone marrow MSC-derived microvesicles (bmMSC-MVs) on acute pancreatitis (AP).
  • To elucidate the underlying mechanisms by which bmMSC-MVs exert their protective effects in AP models.

Main Methods:

  • bmMSC-MVs were isolated from Sprague-Dawley rats.
  • Acute pancreatitis (AP) models were established in vivo (cerulein-induced mild AP and sodium taurocholate-induced severe AP) and in vitro.
  • Pancreatic injury markers (serum amylase, lipase, cytokines) and NF-κB signaling were assessed.

Main Results:

  • bmMSC-MVs significantly attenuated pancreatic injury in both mild and severe AP models.
  • Treatment with bmMSC-MVs reduced levels of pro-inflammatory cytokines (IL-1α, IL-6, TNF-α).
  • bmMSC-MVs inhibited NF-κB p65 nuclear translocation and improved pancreatic acinar cell survival in vitro.

Conclusions:

  • Bone marrow MSC-derived microvesicles exhibit a protective role in acute pancreatitis.
  • bmMSC-MVs reduce inflammation by decreasing pro-inflammatory cytokines and regulating NF-κB signaling.
  • bmMSC-MVs represent a promising cell-free therapeutic strategy for severe acute pancreatitis (SAP).

Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
