Human Embryo Development Set
Chronological Morphological Mapping: A comprehensive 8-model series featuring enlarged representations of the zygote, cleavage, blastocyst, and sequential embryonic stages to illustrate early organogenesis.
Integrated Gestational Hardware: Each specimen is mounted on an individual reinforced pedestal, allowing for 360-degree tactile inspection of the neural tube, branchial arches, and limb bud emergence.

Quick Answer: The human embryo development set is a series of models showing how a human develops over time, from the fertilised egg through early cell divisions to the embryo. It is used in biology, nursing, midwifery and medical teaching to put the stages of prenatal development in their correct order.
Putting the First Weeks in Order
A single embryo model shows one moment; a human embryo development set shows the sequence. Sets of this kind typically begin with the zygote, the single fertilised cell formed in the uterine tube, then show cleavage into 2, 4 and 8 cells, the solid morula of about 16 cells and the hollow blastocyst that reaches the uterus. Later models show implantation into the uterine lining, the flat embryonic disc and the folded embryo with somites and limb buds, and some sets continue into the early fetal period.
Timing is a common examination topic, and the set lets students lay the stages out along a timeline. The morula forms around day three or four; the blastocyst enters the uterus and begins to implant at about day six or seven; gastrulation in the third week lays down the three germ layers; and by the end of the eighth week the main organs have formed and the embryo becomes a fetus.
The number of models, the stages chosen, their scale and whether they share one base are not given in the title and vary between sets. Buyers comparing it with the human embryo set in PVC should check which stages each includes.

Care & Handling
- Keep each model of the human embryo development set in its labelled place so the sequence stays complete and in order.
- Handle the smallest stages by their bases; tiny cell clusters chip easily.
- Clean with a dry, soft brush and keep the set out of strong sunlight.
Applications
- Arranging the stages of development in order as a class activity
- Teaching fertilisation, cleavage, implantation and gastrulation in biology and medical courses
- Midwifery and nursing lessons linking gestational age to development
- Explaining IVF, where embryos are cultured to the blastocyst stage
Why Choose LabEquip
Biology departments and health science colleges buy development sets so the sequence of early life can be handled and ordered rather than memorised from a list. LabEquip lists the set in its biology lab products; ask through the contact page which stages it includes.
Frequently Asked Questions
What is the difference between a morula and a blastocyst?
A morula is a solid ball of about 16 cells formed a few days after fertilisation. A blastocyst follows it: fluid collects inside to form a cavity, an inner cell mass gathers at one side to become the embryo, and an outer layer, the trophoblast, will help form the placenta.
When does implantation happen?
It begins about six to seven days after fertilisation, when the blastocyst attaches to the lining of the uterus and starts to burrow in. It is usually complete by the end of the second week.
What is gastrulation?
It is the process in the third week when the embryonic disc forms three germ layers: ectoderm, mesoderm and endoderm. Every tissue of the body develops from one of these layers, for example the nervous system from ectoderm and the gut lining from endoderm.
How is gestational age different from embryonic age?
Gestational age is counted from the first day of the last menstrual period, while embryonic age is counted from fertilisation, about two weeks later. A pregnancy described as 10 weeks therefore carries an embryo or fetus about 8 weeks old, which matters when reading development charts.
Why is a set more useful than a single model for this topic?
Development is a sequence, and the key ideas are change and timing. With several stages side by side, students can see the embryo grow and fold, and teachers can test understanding by asking them to arrange the models in order.
At which stage are embryos transferred in IVF?
Embryos are commonly transferred either at the cleavage stage, around two to three days after fertilisation, or at the blastocyst stage, around day five. The set helps students see what these stages look like.
