Stages Of Fertilization - Monash Biotech.pdf

Fertilization marks the beginning of a new life! Let's explore the incredible transformation that takes place within the first week, focusing on the key cell stages.

2. FertilizationFertilization
This is where the magic happens! A single sperm fuses
with an egg, creating a single-celled structure called a
zygote.
The zygote holds the combined genetic information from
both parents, a blueprint for the developing embryo.

3. ZYGOTEZYGOTE
(Day 1)(Day 1)
This tiny champion, the zygote, is busy preparing for cell
division.
It undergoes rapid internal changes to initiate this
essential process.

4. Embryo (Days 2Embryo (Days 2
BlastocystBlastocyst
Stage)Stage)
While the term "embryo" can technically encompass all
stages of development following fertilization, it's often
used specifically to refer to the multicellular stages after
the zygote.
So, from the 2-cell stage onwards, the developing
organism is considered an embryo.

5. 2 Cells (Day 2)2 Cells (Day 2)
The zygote divides for the first time, creating two
identical daughter cells.
These are called blastomeres. This marks the beginning of
the cleavage stage.

6. 4 Cells (Day 2)4 Cells (Day 2)
Another cell division occurs, resulting in four blastomeres.
These early blastomeres are totipotent, meaning each one
has the potential to develop into any cell type in the
embryo!

7. 8 Cells (Day 3)8 Cells (Day 3)
Continued cell division leads to the formation of eight
blastomeres.
This rapid multiplication continues as the embryo travels
down the fallopian tube towards the uterus.

8. MorulaMorula
(Days 4 - 5)(Days 4 - 5)
As the number of blastomeres reaches around 16-32, they
start to compact together, forming a solid ball of cells
called a morula.
It resembles a mulberry, hence the name (morus means
mulberry in Latin).

9. 32 Cells32 Cells
(Day 4 - 5)(Day 4 - 5)
This is an estimate, as the exact number of cells in the
morula can vary.
What's important is that the blastomeres continue to
divide and differentiate, laying the foundation for further
development.

10. BlastocystBlastocyst
(Days 5 - 7)(Days 5 - 7)
The morula undergoes a remarkable transformation. A fluid-
filled cavity called the blastocoel forms within it. The outer
layer of cells flattens and becomes the trophectoderm,
which will contribute to the placenta, the lifeline between
mother and embryo. The inner cell mass (ICM) differentiates
into a cluster of cells with the potential to develop into the
fetus itself.
The blastocyst is a marvel of nature, a complex structure
poised for the next crucial step: implantation in the uterine
lining. This marks the official beginning of pregnancy!

11. Blastocyst (Days 5 - 7)Blastocyst (Days 5 - 7)

poised for the next crucial step: implantation in the
uterine lining. This marks the official beginning of
pregnancy!
