Resumen
La termofotobiomodulación (TPBM) aumenta temporalmente las células madre mesenquimales (MSC) en la médula ósea y el bazo. Las sesiones repetidas de TPBM mejoran el crecimiento de las MSC en el área lesionada, favoreciendo la regeneración de tejidos.
Área de la Ciencia:
- Ingeniería Biomédica
- Medicina Regenerativa
- Biología de Células Madre
Sus antecedentes:
- Las células madre mesenquimales (MSC) son cruciales para la reparación y regeneración de tejidos.
- La fotobiomodulación es un enfoque terapéutico emergente para la curación de tejidos.
- Comprender los efectos sistémicos de las terapias en las MSC es vital para la traslación clínica.
Objetivo del estudio:
- Investigar los efectos sistémicos de la termofotobiomodulación (TPBM) en las MSC.
- Evaluar la influencia de las sesiones repetidas de TPBM in vivo.
- Evaluar el impacto de la irradiación láser localizada en la distribución de las MSC.
Principales métodos:
- Las ratas se sometieron a irradiación localizada con láser (970 nm) de la médula ósea tibial.
- Se analizaron las cuentas de MSC en la médula ósea y el bazo después de la irradiación.
- Se realizaron comparaciones entre sesiones únicas y repetidas de TPBM.
Principales resultados:
- La TPBM aumentó significativamente las cuentas de MSC temporalmente tanto en tejidos irradiados como distantes.
- Las sesiones repetidas de TPBM demostraron un crecimiento mejorado de las MSC en el área lesionada en comparación con las sesiones únicas.
- El estudio observó la movilización y regulación sistémica de las MSC por la TPBM.
Conclusiones:
- La TPBM influye eficazmente en la distribución y proliferación de las MSC de forma sistémica.
- Las sesiones repetidas de TPBM muestran potencial para una mayor capacidad regenerativa.
- Estos hallazgos respaldan la TPBM como una estrategia prometedora para la terapia celular y la regeneración de tejidos.

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...

Adult Stem Cells

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...

Embryonic Stem Cells
32.6K
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

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...

Second Order systems II
412
In an underdamped second-order system, where the damping ratio ζ is between 0 and 1, a unit-step input results in a transfer function that, when transformed using the inverse Laplace method, reveals the output response. The output exhibits a damped sinusoidal oscillation, and the difference between the input and output is termed the error signal. This error signal also demonstrates damped oscillatory behavior. Eventually, as the system reaches a steady state, the error diminishes to zero.
