Cell Culture

Cell Culture

Most vertebrate cells grow in vitro attached to a substrate as a monolayer, called adherent cultures. The flasks and plates used to grow cells are chemically treated to facilitate cell attachment. However, a few cell types, such as hematopoietic cells, can grow in a suspension. In contrast to adherent cultures, suspension cultures can grow in non-treated cultureware using magnetic stirrers or spinner flasks to agitate the culture media

Stem Cell Culture

Stem Cell Culture

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...

Plant Tissue Culture

Plant Tissue Culture

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

Base Excision Repair

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

DNA Base Pairing

DNA Base Pairing

Erwin Chargaff’s rules on DNA equivalence paved the way for the discovery of base pairing in DNA. Chargaff’s rules state that in a double-stranded DNA molecule,

Lewis Acids and Bases

Lewis Acids and Bases

In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Area of Science:

Biotechnology
Stem Cell Biology
Cell Migration Studies

Background:

Development of a 4D cell culture platform for observing single hematopoietic stem cell (HSC) migration.
Integration of polymer film microcavity arrays within a microtiter plate format.

Purpose of the Study:

To detect and characterize the migration dynamics of single HSCs.
To evaluate the platform as an artificial HSC niche model using co-cultures.

Main Methods:

Utilized CD34-expressing KG-1a cells as a surrogate for HSCs.
Established a 21-day co-culture model of human HSCs (hHSCs) and human mesenchymal stromal cells (hMSCs).
Employed software-based cell detection for counting HSCs within microcavities.

Main Results:

Successfully detected individual HSCs and their migration patterns within microcavities.
Observed distinct HSC populations at the bottom and middle of microcavities at day 14.
Noted the merging of HSC populations by day 21, obscuring distinct localization.

Conclusions:

Demonstrated the feasibility of detecting single HSC migration using the developed platform.
Highlighted non-uniform data sets obtained from microscopy and flow cytometry.
Indicated ongoing optimization efforts for the platform and data analysis.
