Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

3.8K
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...

Stem Cell Culture

5.3K
Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...

Stem Cell Niche01:26

Stem Cell Niche

5.2K
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...

Purposive Learning01:22

Purposive Learning

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

4.1K
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.

Embryonic Stem Cells00:58

Embryonic Stem Cells

28.9K
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.

Area of Science:

  • Education
  • STEM Education
  • Gifted Education

Background:

  • Many students, particularly those from underrepresented groups, are often overlooked for gifted programs.
  • A gap exists in preparing these students for advanced Science, Technology, Engineering, and Mathematics (STEM) coursework.
  • Effective university-school collaborations are crucial for equitable STEM talent development.

Purpose of the Study:

  • To describe a university-school collaboration designed to prepare underidentified and underserved students for advanced STEM coursework.
  • To evaluate the impact of early intervention and extensive STEM programming on student achievement and higher education matriculation.
  • To identify best practices for STEM talent identification and development pathways.

Main Methods:

  • A collaboration between a university and school district provided early intervention, over 400 hours of out-of-school STEM programming, tutoring, and family support.
  • Longitudinal data (Grade 3-8) on standardized achievement tests were collected for 361 African American and/or Hispanic students across 14 cohorts.
  • Student outcomes included Grade 9 accelerated mathematics placement and college matriculation rates, compared to demographic peers.

Main Results:

  • Students demonstrated greater reading and mathematics growth compared to district peers, achieving levels comparable to the highest-scoring students.
  • Significant increases were observed in the percentage of students entering high school with advanced placement in mathematics.
  • Multiple cohorts showed improved matriculation rates at more selective higher education institutions.

Conclusions:

  • The described collaboration effectively prepared underserved students for advanced STEM coursework, enhancing academic achievement and college readiness.
  • Early intervention, sustained STEM engagement, and family support are key components of successful STEM talent development.
  • Findings inform best practices for identifying and nurturing STEM talent in diverse student populations through university-school partnerships.
