まとめ
鼻腔内骨髄間葉系幹細胞(BMSC)療法は、多発性硬化症(MS)のマウスモデルにおいて運動機能の改善と脳構造の維持をもたらした。間欠的な कपrizone曝露は、神経保護および再生におけるBMSCの有効性を高めた。
科学分野:
- 神経科学
- 再生医療
- 幹細胞治療
背景:
- MSは、組織学的変化とそれに続く行動学的欠損を特徴とする。
- 骨髄間葉系幹細胞(BMSC)は、MS治療の可能性を示している。
- 本研究では、間欠的 कपrizone誘発(INT-CPZ)MSモデルにおける鼻腔内BMSC投与を調査する。
主な方法:
- マウスを対照群、CPZ群、CPZ+BMSC群、INT-CPZ群、INT-CPZ+BMSC群の5群に分けた。
- BMSCは4週目と10週目に鼻腔内投与した。
- ビームウォーキング、ポール、ラダーラングテストで運動能力を評価し、立体測定法で小脳構造を分析した。
結論:
- 鼻腔内BMSC療法は、 कपrizone曝露マウスにおける小脳構造および運動機能の維持に有効である。
- 間欠的 कपrizone曝露はBMSCの有効性を増強し、神経再生および神経保護メカニズムの亢進を示唆する。
- 本研究は、MSの治療戦略としての鼻腔内BMSC投与の可能性を強調する。

Mesenchymal Stem Cells
5.6K
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...

Induced Pluripotent Stem Cells
28.1K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
263
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

Bone Marrow Sampling and Transplants
1.2K
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Adult Stem Cells
33.9K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...
