Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Age-related diseases are associated with multiple defects in components of the cytoplasm. Here, we present a protocol to prepare plasma membrane vesicles from bone marrow mesenchymal stem cells. This technique could potentially be used as a means of cytoplasm replacement therapy to ameliorate or even reverse age-associated phenotypes.

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...

Here we present a cell-based flow cytometry method to detect neutralizing antibodies or other factors that interfere with the cellular uptake of enzyme replacement therapies in a human matrix, such as cerebral spinal fluid (CSF) or human serum.
FAQs
The transplanted cells must match the functional requirements of the damaged neural region. Stem cell-derived or specialized neural cells may need to mature into appropriate cell types, release relevant neurotransmitters, and establish connections with host circuits. If cell identity does not suit the target region, survival alone may not restore neural function or produce meaningful circuit-level repair.
Transplanted cells must remain viable in the target region long enough to mature and participate in neural repair. Immune compatibility is also important because incompatibility can undermine cell persistence and integration. These factors work together with delivery conditions and the local tissue environment, making successful transplantation dependent on more than simply introducing cells into nervous tissue.
After reaching the target region, transplanted cells may mature, release neurotransmitters, and form functional connections with host neural circuits. These activities provide possible mechanisms for influencing disrupted signaling rather than merely occupying damaged tissue. Researchers therefore assess whether the cells become functionally appropriate and interact with existing circuits, not only whether they remain present.
Development focuses on several linked requirements: selecting an appropriate cell identity, delivering cells to the relevant target region, supporting their survival, achieving immune compatibility, and promoting integration with host circuits. Evaluating these elements helps researchers determine why a treatment succeeds or fails and whether introduced cells can contribute to restored neural function.
Research includes disorders involving neuronal loss, with Parkinson’s disease and spinal cord injury identified as important examples. These conditions provide distinct contexts for studying whether introduced cells can survive, mature, release neurotransmitters, and connect with remaining neural circuitry. The broader goal is to examine whether replacing lost cellular functions can support repair in damaged nervous systems.
Studies can examine whether transplanted cells survive in the target region, mature into appropriate neural cell types, release neurotransmitters, and form functional connections with host circuits. They also assess delivery, immune compatibility, and integration. Together, these outcomes indicate whether the intervention has progressed beyond cell persistence toward potential restoration of tissue function.
