NaNog: A pluripotency homeobox (master) molecule. [PDF]

open access: yes, 2015
One of the most intriguing aspects of cell biology is the state of pluripotency, where the cell is capable of self-renewal for as many times as deemed necessary , then at a specified time can differentiate into any type of cell. This fundamental process

The role of roof plate-specific spondins in liver homeostasis and disease

open access: yesLiver Research, 2022
As evolutionarily conserved signals, roof plate-specific spondins (R-spondins; RSPOs) are a family with four members (RSPO1–4) exerting distinctly different functions.

The effects of different combinations and varying concentrations of growth regulators on the regeneration of selected Turkish cultivars of melon [PDF]

open access: yes, 2013
Cucurbits are an economically important family of plants. The majority of the vegetable production in Turkey, for example, derives from the species beloning to the family Cucurbitaceae. Despite the importance of cucurbits among vegetable crops worldwide,

Rac1 drives intestinal stem cell proliferation and regeneration [PDF]

open access: yes, 2013
Adult stem cells are responsible for maintaining the balance between cell proliferation and differentiation within self-renewing tissues. The molecular and cellular mechanisms mediating such balance are poorly understood.

Organismic Supercategories and Qualitative Dynamics of Systems [PDF]

open access: yes, 1971
The representation of biological systems by means of organismic supercategories, developed in previous papers, is further discussed. The different approaches to relational biology, developed by Rashevsky, Rosen and by Baianu and Marinescu, are compared ...

Akt1-Inhibitor of DNA binding2 is essential for growth cone formation and axon growth and promotes central nervous system axon regeneration. [PDF]

open access: yes, 2016
Mechanistic studies of axon growth during development are beneficial to the search for neuron-intrinsic regulators of axon regeneration. Here, we discovered that, in the developing neuron from rat, Akt signaling regulates axon growth and growth cone ...

Characterization of Human Induced Pluripotent Stem Cell-Derived Retinal Pigment Epithelium Cell Sheets Aiming for Clinical Application

open access: yesStem Cell Reports, 2014
Age-related macular degeneration (AMD) causes severe visual impairment due in part to age-dependent impairment of retinal pigment epithelium (RPE). It has been suggested that autologous human induced pluripotent stem cells (hiPSCs) may represent a useful

The human ARF tumor suppressor senses blastema activity and suppresses epimorphic tissue regeneration. [PDF]

open access: yes, 2015
The control of proliferation and differentiation by tumor suppressor genes suggests that evolution of divergent tumor suppressor repertoires could influence species regenerative capacity.

The Cellular and Physiological Basis for Lung Repair and Regeneration: Past, Present, and Future. [PDF]

open access: yes, 2020
The respiratory system, which includes the trachea, airways, and distal alveoli, is a complex multi-cellular organ that intimately links with the cardiovascular system to accomplish gas exchange.
