Stem Cell Regulation Using Nanofibrous Membranes with Defined Structure and Pore Size

Description: Electrospun nanofibers have been researched extensively in the culturing of stem cells to understand their behavior since electrospun fibers mimic the native extracellular matrix (ECM) in many types of mammalian tissues. Here, electrospun nanofibers with defined structure (orientation/alignment) and pore size could significantly modulate human mesenchymal stem cell (hMSC) behavior. Controlling the fiber membrane pore size was predominantly influenced by the duration of electrospinning, while th… more

Understanding Melanocyte Stem Cells for Disease Modeling and Regenerative Medicine Applications

Description: This review highlights recent studies and progress involved in understanding the development of cutaneous melanocytes and the regulation of McSCs. Melanocytes in the skin play an indispensable role in the pigmentation of skin and its appendages. It is well known that the embryonic origin of melanocytes is neural crest cells. In adult skin, functional melanocytes are continuously repopulated by the differentiation of melanocyte stem cells (McSCs) residing in the epidermis of the skin.

A Comprehensive Approach to Addressing Gender Equity in STEM Subjects at Four-Year Universities in England

Description: This chapter explores gender disparities in enrollment and persistence in STEM undergraduate education in England. The authors examine the difference in early educational achievement in mathematics and science subjects and students’ plan to study STEM subjects by gender. They also examine women’s odds of studying STEM subjects in England after controlling for academic performance and social class characteristics. The authors also particularly test gendered differences in studying STEM at presti… more

STEM Bachelor's Degree Attainment among Women of Color in the United States: Using Geographic Analysis for Gender and Racial Equity Research

Description: This chapter showcases a study that examines the relationship between STEM bachelor’s degree attainment, particularly focusing on women of color, and the opportunities of higher education and STEM higher education within local communities across the United States. The authors analyze two large-scale national data sets, the Integrated Postsecondary Education Data System (IPEDS) and the American Community Survey (ACS), to conduct a location-level analysis. The authors then offer implications that… more

Atomic Resolution Imaging with a sub-50 pm Electron Probe

Description: Using a highly coherent focused electron probe in a 5th order aberration-corrected transmission electron microscope, we report on resolving a crystal spacing less than 50 pm. Based on the geometrical source size and residual coherent and incoherent axial lens aberrations, an electron probe is calculated, which is theoretically capable of resolving an ideal 47 pm spacing with 29percent contrast. Our experimental data show the 47 pm spacing of a Ge 114 crystal imaged with 11-18percent contrast at… more

A molecular link between stem cell regulation and floral patterning in Arabidopsis.

Description: OAK-B135 The homeotic gene AGAMOUS (AG) has dual roles in specifying floral organ fate and limiting stem cell proliferation in Arabidopsis flowers. We show here that the floral identity protein LEAFY (LFY), a transcription factor expressed throughout the flower, acts together with the homeodomain protein WUSCHEL (WUS) to activate AG in the center of flowers. WUS was previously identified because of its role in maintaining a stem cell population in the center of both shoot and floral meristems. … more

Effect of the Resistance Exercise-Induced Hormonal Changes on Satellite Cell Myogenic State

Description: Skeletal muscle satellite cells are important for muscle repairing and muscle mass growth. For a successful muscle regenerative process, satellite cells have to sequentially undergoing different stages of myogenic process, i.e. proliferative state and differentiation state. To support this process, the presence of different circulating factors, such as immune cells, cytokines, and hormones, at the appropriate time course is critical. Among these factors, hormones, such as testosterone, cortisol… more

Optimization of In Vitro Mammalian Blastocyst Development: Assessment of Culture Conditions, Ovarian Stimulation and Experimental Micro-Manipulation

Description: Factors currently at the forefront of human in vitro fertilization (IVF) that collectively influence treatment success in the form of blastocysts development were investigated during early mammalian embryology with concentration on infertile patients presenting with diminished ovarian reserve or preliminary ovarian failure. A novel experimental technique, Graft Transplant-Embryonic Stem Cells (GT-ESC) was introduced in the mouse model, as the first inclusive approach for embryo selection in IVF… more

Personalities and Pipelines: Exploring the Role of Personality in Student Self-selection Into Stem Majors

Description: Despite all the national efforts to increase STEM enrollment in the United States, the gap between the U.S. and other developed countries in terms of STEM graduates has widened over the last 20 years. Researchers have studied factors such as gender, race, high school GPA, and the student’s socioeconomic status for their impact on STEM enrollment. This study offers another possible explanation of why students might choose, or not choose, to enroll in STEM majors by examining the relationship bet… more

Design and Performance Characteristics of the ORNL AdvancedMicroscopy Laboratory and JEOL 2200FS-AC Aberration-CorrectedSTEM/TEM

Description: At ORNL, the new Advanced Microscopy Laboratory (AML) has recently been completed, with two aberration-corrected instruments installed, and two more planned in the near future to fill the 4-laboratory building. The installed JEOL 2200FS-AC has demonstrated aTEM information limit of 0.9A. This limit is expected given the measured instrument parameters (HT and OL power supply stabilities, beam energy spread, etc.), and illustrates that the environmental influences are not adversely affecting the … more

Identification of a Potential Factor Affecting Graduation Rates in STEM for Hispanic Students at the University of North Texas, via Analysis of Nonfiction Science Books in Spanish Language for ELLs in the Dallas ISD Schools

Description: Latinos are the largest minority group in the U.S.; however despite the continuous growth of the Hispanic population, Latinos are severely underrepresented in STEM fields. One of the reasons that might explain why Latinos do not major in STEM is the way they encounter science curriculum in primary school. Students' limited proficiency in English may constrain their science achievement when instruction is delivered exclusively in English. A quantitative analysis with graduation rates in STEM fro… more
