Stem Cell Niche01:26

Stem Cell Niche

5.0K
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...

Stem Cell Therapy for Tissue Regeneration

3.8K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

3.0K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Source And Potency Of Stem Cells

5.0K
Stem cells are undifferentiated cells with extensive self-renewal properties that help them maintain their population during the fetal and adult stages of life. They can specialize in all cell types of the human body. However, their differential potential may vary and can be classified into five types. Stem cells can be (1) Totipotent, (2) Pluripotent, (3) Multipotent, (4) Oligopotent, and (5) Unipotent. Each stem cell has a specific origin; the fertilized egg or zygote is a totipotent cell and...

Basic Plant Anatomy: Roots, Stems, and Leaves

The primary organs of vascular plants are roots, stems, and leaves, but these structures can be highly variable, adapted for the specific needs and environment of different plant species.

Social Traps01:41

Social Traps

20.5K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Implant Design

Background:

  • Conventional uncemented femoral implants offer reliable fixation but face challenges in bone stock preservation and minimally invasive surgery.
  • Proximal-distal femoral dimensional mismatch and surgical approach limitations drive innovation in hip implant design.

Purpose of the Study:

  • To evaluate the efficacy and bone remodeling characteristics of uncemented metaphyseal-engaging short stem implants in total hip replacement (THR).
  • To compare the clinical performance of short stem implants with conventional femoral stems.

Main Methods:

  • Analysis of clinical outcomes and radiographic assessments of patients undergoing THR with metaphyseal-engaging short stem implants.
  • Comparison of bone remodeling patterns around short stem implants versus conventional stems.

Main Results:

  • Uncemented metaphyseal-engaging short stem implants demonstrate stable fixation and comparable clinical performance to conventional stems.
  • These short stem designs are associated with proximal bone remodeling closer to the metaphysis.

Conclusions:

  • Short stem metaphyseal-engaging implants represent a viable alternative for THR, addressing limitations of conventional designs.
  • These implants can achieve durable fixation and support high patient function, aligning with successful THR goals.
