Summary
Human stem cell-derived brain models recapitulate synapse development and loss, offering insights into neuronal disorders and potential therapies.
Area of Science:
- Neuroscience
- Stem Cell Biology
- Developmental Biology
Background:
- Brain disorders often involve abnormal synapse development or age-related synapse loss.
- Studying human synapse development and degeneration is complex.
- Human-induced pluripotent stem cells (hIPSCs) offer a novel approach to model these processes.
Purpose of the Study:
- To review the capacity of hIPSC-derived brain models to mimic human synapse development and degeneration.
- To explore insights into molecular mechanisms of synaptic alterations in neurological conditions.
- To discuss the potential of advanced hIPSC models for understanding synapse biology and treatment responses.
Main Methods:
- Engineering neurons and brain organoids from hIPSCs.
- Observing synapse formation (excitatory and inhibitory) and functional activity in these models.
- Reviewing existing literature on hIPSC-derived brain models and synaptic alterations.
Main Results:
- hIPSC-derived brain models successfully develop both excitatory and inhibitory synapses.
- These models exhibit functional synaptic activity, mirroring aspects of human brain development.
- The models provide a platform to study molecular mechanisms of synaptic changes in disease.
Conclusions:
- hIPSC-derived brain models are valuable tools for studying human synapse development and degeneration.
- These models can elucidate molecular mechanisms underlying synaptic alterations in neuronal disorders.
- Advancements in these models hold promise for understanding disease progression and evaluating therapeutic strategies.

133.1K
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.

01:10Zygotic Development And Stem Cell Formation
6.7K
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...

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...

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.

01:28Electrical Synapses
10.7K
Electrical synapses found in all nervous systems play important and unique roles. In these synapses, the presynaptic and postsynaptic membranes are very close together (3.5 nm) and are actually physically connected by channel proteins forming gap junctions.
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...

Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
