High Cholesterol Levels Affect Mobilization Of Cells From Bone Marrow: Implications For Transplants And Understanding Cancer Onset
- Instituto Gulbenkian de Ciência
- Increased cholesterol levels are being increasingly recognized as risk factors for the onset and progression of several cancers. Now researchers in Portugal show that high levels of cholesterol can affect the microenvironment of the bone marrow, so that more cells move from the bone marrow to peripheral, circulating blood.
Increased cholesterol levels are being increasingly recognised as risk factors for the onset and progression of several cancers. Now researchers in Portugal show that high levels of cholesterol can affect the microenvironment of the bone marrow, so that more cells move from the bone marrow to peripheral, circulating blood.
These findings, by Sergio Dias and his team, an external group of the Instituto Gulbenkian de Ciência, have implications for transplantation and further understanding bone marrow malignancies, are to appear in the next issue of the journal Blood.
These finding may have implications for transplants and bone marrow malignances. As Sérgio Dias points out “It is the first time, as far as we are aware, that cholesterol is directly linked to mobilisation of cells in the bone marrow. In a transplant setting, we believe patients with high cholesterol may be less ‘receptive’, since more blood cells exit to the peripheral vessels. Therefore drugs that modulate cholesterol levels may have beneficial effects also in a transplant setting.”
In Vitro Differentiation Assay
Methylcellulose culture was performed following manufacturer’s instructions in a 24-well plate containing 1 × 104 LinSca1+c-Kit+ cells per well and in the presence or absence of LDL or HDL alone or together with Blt3 . The number of colonies was scored after 7 days of culture with the use of an inverted microscope. Colony morphology was assessed on Giemsa-stained cytospins of selected colonies.

Limited Studies On Bone Marrow Consumption
Note that all of the studies above were performed using supplements containing concentrated amounts of individual compounds found in bone marrow.

Though research is limited on the health effects of bone marrow itself, studies show that many of its components could support joint function, decrease inflammation, and promote skin health.
Cholesterol Levels And Hematopoiesis
In the bloodstream, cholesterol is transported within lipoprotein particles, which are organized by apolipoproteins that can be recognized and bound by specific receptors on cell membranes. There are several types of lipoproteins, such as high-density lipoprotein , low-density lipoprotein , intermediate-density lipoprotein , very-low-density lipoprotein , and chylomicrons, in order of higher density to lower density. LDL is the major cholesterol carrier in the blood and is recognized by the LDL receptor in peripheral tissues. LDL is the atherogenic lipoprotein, and increased LDL levels promote cholesterol accumulation. Macrophages accumulate oxidized LDL and give rise to foam cells, and contribute to atherosclerotic plaque formation. HDL opposes this process and reduces inflammation. HDL is involved in reverse cholesterol transport, in which HDL serves to shuttle cholesterol from peripheral tissues to the liver where cholesterol is eventually converted into bile acids.

What Is Bone Marrow
Bone marrow is a type of spongy tissue in the center of bones. Its most concentrated in the spine, hip, and thigh bones.
It contains stem cells that develop into red blood cells, white blood cells, or platelets, which are involved in oxygen transportation, immune function, and blood clotting .
The bone marrow of animals like cows, lambs, caribou, and moose is commonly consumed in many types of cuisine.

- Thiamine: 1% of the RDI
- Vitamin A: 1% of the RDI
Bone marrow provides a small amount of the B vitamins pantothenic acid, thiamine, and biotin, which are needed for important bodily processes, including energy production .
Animals And Experimental Design
All animal experiments were performed with the approval of the Instituto Gulbenkian de Ciencia Animal Care Committee and Review Board. C57Bl/6j mice were subject to a 30-day high-cholesterol feeding trial. In brief, groups of 6 animals were put on a high-fat/high-cholesterol/cholate diet , with food and water ad libitum; animals were killed after 30 days on the diet. In parallel, groups of 6 animals were fed the standard mouse diet and were used as controls.

What Is Cholesterol
Cholesterol is a fat-like substance suspended in your blood. It is made by your liver and is also found in some foods you eat.
Your total cholesterol blood test value includes three parts:
LDL; cholesterol is “bad” cholesterol. When too much LDL builds up on your artery walls, plaque forms and blocks blood flow. This can cause heart disease, peripheral artery disease and stroke.
HDL; cholesterol is the “good” cholesterol. HDL helps to get rid of extra cholesterol from your blood and tissue. This may prevent or reverse blood vessel problems by taking the cholesterol from the plaque.
Triglycerides;is a fat digested from food that is released into your bloodstream. It either gives your body energy or it is stored as fat. Triglycerides come from dietary fat, high sugar foods, too much alcohol or too many calories.

Perspectivelipids In The Bone Marrow: An Evolving Perspective
Because of heavy energy demands to maintain bone homeostasis, the skeletal system is closely tied to whole-body metabolism via neuronal and hormonal mediators. Glucose, amino acids, and fatty acids are the chief fuel sources for bone resident cells during its remodeling. Lipids, which can be mobilized from intracellular depots in the bone marrow, can be a potent source of fatty acids. Thus, while it has been suggested that adipocytes in the bone marrow act as filler and are detrimental to skeletal homeostasis, we propose that marrow lipids are, in fact, essential for proper bone functioning. As such, we examine the prevailing evidence regarding the storage, use, and export of lipids within the skeletal niche, including from both in;vitro and in;vivo model systems. We also highlight the numerous challenges that remain to fully appreciate the relationship of lipid turnover to skeletal homeostasis.

Cholesterol Has Minor Effects On The Cxcr4 Promoter Activity
Having shown that LDL promotes SDF-1 production by endothelial cells and promotes HC migration induced by SDF-1, next we determined whether LDL also regulated CXCR4 expression. By using leukemia cells lines representative of the hematopoietic lineages mobilized by high cholesterol , we observed that LDL does not significantly affect CXCR4 promoter activity on lymphoid or monocytic cells but reduces it on MK cells ; interestingly, we observed that SDF-1 strongly induced CXCR4 promoter activity .
