Heterogeneity of Embryonic and Adult Stem Cells [PDF]

open access: yesCell Stem Cell, 2008
New studies suggest that stem cells of embryonic, neural, and hematopoietic origin are heterogeneous, with cells moving between two or more metastable states. These cell states show a bias in their differentiation potential and correlate with specific patterns of transcription factor expression and chromatin modifications.

The circular SiZer, inferred persistence of shape parameters and application to early stem cell differentiation [PDF]

open access: yesBernoulli 2016, Vol. 22, No. 4, 2113-2142, 2014
We generalize the SiZer of Chaudhuri and Marron (J. Amer. Statist. Assoc. 94 (1999) 807-823, Ann. Statist. 28 (2000) 408-428) for the detection of shape parameters of densities on the real line to the case of circular data. It turns out that only the wrapped Gaussian kernel gives a symmetric, strongly Lipschitz semi-group satisfying "circular ...

Adult Stem and Progenitor Cells

open access: yes, 2009
The discovery of adult stem cells in most adult tissues is the basis of a number of clinical studies that are carried out, with therapeutic use of hematopoietic stem cells as a prime example. Intense scientific debate is still ongoing as to whether adult stem cells may have a greater plasticity than previously thought. Although cells with some features

FoxO1 signaling in B cell malignancies and its therapeutic targeting

open access: yesFEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

Bioengineered liver crosslinked with nano-graphene oxide enables efficient liver regeneration via MMP suppression and immunomodulation

open access: yesNature Communications, 2023
Bioengineered livers using decellularized scaffolds have been considered as an alternative to donor organs. Here, the authors modulate biophysical properties of decellularized scaffolds by crosslinking with nano-graphene oxide, thereby greatly enhancing ...

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Perspectives for Clinical Translation of Adipose Stromal/Stem Cells

open access: yesStem Cells International, 2019
Adipose stromal/stem cells (ASCs) are an ideal cell type for regenerative medicine applications, as they can easily be harvested from adipose tissue in large quantities.

Use of Mesenchymal Cells to Modulate Immune Suppression and Immune Reconstruction in a Patient with Aplastic Anemia Complicated by Invasive Sino-Orbital Aspergillosis

open access: yesTurkish Journal of Hematology, 2014
Cultured human bone marrow mesenchymal cells (MSCs) have immunomodulatory and tissue regenerative properties. This report summarizes the result of post-transplant treatment with MSCs of a 26-year-old patient with aplastic anemia complicated by invasive ...
