Insights

Kidney organoids derived from pluripotent stem cells offer new ways to study glomerular podocytes in development and disease. This research reviews advancements and challenges in podocyte research using organoid technology.

Area of Science:

  • Nephrology
  • Developmental Biology
  • Stem Cell Biology

Background:

  • Glomerular podocytes are crucial for kidney function and a key research focus.
  • Human kidney organoids derived from pluripotent stem cells provide a model for studying podocyte development and disease.
  • Recent single-cell RNA-sequencing of human kidneys offers molecular insights into podocyte lineage.

Purpose of the Study:

  • To review recent progress in podocyte research using kidney organoids.
  • To discuss the limitations and future directions of organoid technology for studying podocyte biology.
  • To highlight the application of organoids in modeling hereditary podocyte diseases.

Main Methods:

  • Generation of kidney organoids from pluripotent stem cells.
  • Analysis of podocyte gene and protein expression in organoids.
  • Experimental transplantation of kidney organoids.
  • Single-cell RNA-sequencing of human fetal and adult kidneys.

Main Results:

  • Podocytes in kidney organoids express key slit diaphragm genes and proteins.
  • Organoid-derived podocytes show characteristic morphology, enhanced by transplantation.
  • Organoid technology can reproduce hereditary podocyte diseases.
  • Single-cell RNA-sequencing provides reference data for immature organoid podocytes.

Conclusions:

  • Kidney organoids are a powerful tool for advancing podocyte research in development and disease.
  • Further refinement of organoid technology and integration with single-cell data are needed.
  • Organoids hold promise for understanding and treating podocyte-related kidney disorders.

Zygotic Development And Stem Cell Formation

The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...

Embryonic Stem Cells

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.

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Adult Stem Cells01:33

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells

A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
