In the mouse model, forced expression of the Myc oncogene in B-cells causes the mice to develop B-cell lymphomas by 4 to 6 months of age. (sciencedaily.com)
To test the effect of decreasing p53 to particular levels via RNA interference, the scientists reconstituted the blood cells of mice by first irradiating the animals to destroy their endogenous, bone marrow supply of hematopoietic stem cells, and then injected the mice with a fresh supply of hematopoietic stem cells that had been engineered through RNAi to produce low, medium, or high levels of p53.

Similar to lymphomas that form in the absence of p53, lymphomas that formed in mice with low p53 levels developed rapidly (reaching terminal stage after 66 days, on average), infiltrated lung, liver, and spleen tissues, and showed little apoptosis or "programmed cell death. (sciencedaily.com)

Scientists at UC San Diego have discovered that stem cells' unique method of discarding misfolded proteins could hold the key to preserving long-term health and avoiding illness. (scitechdaily.com)
According to a study recently published in the journal Cell Stem Cell , scientists at the University of California San Diego School of Medicine discovered that blood stem cells employ a surprising technique to eliminate their misfolded proteins. (scitechdaily.com)
This helps them make fewer mistakes in the process, as misfolded proteins can become toxic to cells if allowed to build up. (scitechdaily.com)
In most cells, damaged or misfolded proteins get individually tagged for disposal. (scitechdaily.com)
This left the team puzzled: if getting rid of damaged proteins is so important to stem cells, why is the proteasome less active? (scitechdaily.com)
UC San Diego scientists found misfolded proteins were aggregated and caged into a single area (green) within stem cells before being disposed of. (scitechdaily.com)
A main advantage of the proteasome method is that it breaks proteins down immediately, producing amino acids that the cell can reuse to build new proteins. (scitechdaily.com)
But stem cells are less interested in building new proteins. (scitechdaily.com)
Thus the authors suggest that by storing a collection of damaged proteins in one place, stem cells may be creating their own cache of resources that can be used at a later time when they are actually needed, such as after an injury or when it is time to regenerate. (scitechdaily.com)
Specifically, it is in chromatin (the mixture of DNA and proteins that makeup chromosomes) where the genetic regulation processes occur that give rise to the great variety of cell types in the blood. (cun.es)

Counting your baby's cord blood stem cells: What do TNC, CD34+, CFU and other numbers mean? (cryo-cell.com)
The goal of cord blood banking is to capture as many stem cells as possible, but how do you know if your baby's cord blood collection is a good one? (cryo-cell.com)
There are currently several methods you can use to assess the potential future effectiveness of your child's cord blood collection including the collection's volume (in milliliters), the number of total cells (TNC count), the number of stem cells (CD34+ count), and a measurement of the stem cell functionality and potency (such as a colony-forming unit [CFU] count). (cryo-cell.com)
So more cord blood often equates to more cells, which often correlates to more stem cells, which often equates to better potency. (cryo-cell.com)
The simplest way to judge the possible effectiveness of a cord blood collection is its initial overall volume. (cryo-cell.com)
Increases in the volume of a cord blood correlate with increases in stem cells post-processing. (cryo-cell.com)
As a parent, you can expect your doctor to collect anywhere from 60 mL to 90 mL, or more, of cord blood. (cryo-cell.com)
The total nucleated cell (TNC) count is the most widely used and re-producible method for determining the relative potency of a cord blood collection. (cryo-cell.com)
To count the number of total nucleated cells, a sample of the cord blood is run through a hematology analyzer, which produces a complete blood count (CBC) just as your physician does for your yearly check-up. (cryo-cell.com)
Parent's Guide to Cord Blood (PGCB) says the median number of total nucleated cells in a 60 mL cord blood collection is 47.0 x 10 7 , or 470 million cells. (cryo-cell.com)
We've found the median number of total nucleated cells in our clients' collections, again, leaned toward the minimums required by public cord blood banks and were higher than those reported from private banks. (cryo-cell.com)
To better determine the number of hematopoietic stem cells in a cord blood collection, scientists can also look for a specific protein on the surface of the cell. (cryo-cell.com)
To count the number of cells that are positive for the CD34 protein (CD34+), a sample of the cord blood is mixed with a fluorescent dye that adheres to the CD34 antigen. (cryo-cell.com)
PGCB says the median private cord blood collection of 60 mL equates to 1.8 million cells with the CD34 antigen. (cryo-cell.com)
While the number of stems cells in any cord blood collection is important, the ability for those stem cells to function and multiply after infusion is even more important. (cryo-cell.com)

The gene Igf2bp2 is important in youth for the full function of these cells, as it activates their growth and metabolism. (idw-online.de)
When the gene is missing, however, the aging-associated loss of function of the stem cells is surprisingly diminished. (idw-online.de)
The eventual aging of hematopoietic stem cells is apparently already preprogrammed by their gene-driven growth in youth. (idw-online.de)
After that, the gene is silenced and loses its function, it shows hardly any activity in the stem cells in advanced age," explains Prof. K. Lenhard Rudolph, research group leader at the FLI and professor of molecular medicine at FSU Jena. (idw-online.de)
This suggests that Igf2bp2 gene function in early life leads to the aging of the stem cells. (idw-online.de)
The Igf2bp2-gene drives growth and metabolic activity at a young age but these activities contribute to the age-associated loss of hematopoietic stem cell function in later life. (idw-online.de)
Specifically, they have focused on characterizing the gene regulation mechanisms that cells use to decide when and to what extent a gene is activated or deactivated (gene expression). (cun.es)

There was an increase in calcium in the cells when 390 was added, indicating that the receptor was being activated. (vanderbilt.edu)
CXCR4 is a chemokine receptor, and is found on a variety cells, including cancerous and stem cells [1]. (vanderbilt.edu)
As a CXC-type chemokine receptor, or a receptor that responds to CXC chemokines, CXCR4 aids in cell chemotaxis when it is stimulated by chemokines [2]. (vanderbilt.edu)
Many types of cancer cells express the CXCR4 receptor and studies have shown that interference with the activation of the receptor by SDF- inhibited the spread of the cancer cells [3]. (vanderbilt.edu)
This receptor is also used by the HIV-1 virus to infect human body cells [6]. (vanderbilt.edu)
