Breakthrough in Cattle IVP Technology

What is your lab’s current cattle IVP blastocyst rate from abattoir-collected oocytes?  30% from fertilized oocytes? Or is it more like 40%, or even 50%?  What about over 70%?  Have you ever seen those results over several runs, months apart?

ART Lab Solutions is announcing that we have made a breakthrough in IVP technology, where over 70% of fertilized oocytes (over 60% of all oocytes) form good quality blastocysts.  And no CO2 atmosphere or special gas mix is required for IVM, making it ideal for “Transport IVM”.

TIVM Data

Figure 1. COCs matured in Transport VitroMat for 24 hours in 38.5°C environment. Represented as pooled data from 230 COCs over several experimental replicates.

The high development rate (>70%) from our media is a result of over 25 years of research, development and industry consultation, led by the company’s founder, Professor Jeremy Thompson. Industry standard rates rarely exceed 40%.


How ART media compared to a published well-known media

The below experiment completed in a lab by a researcher indicated how our media “ART media” compares to a published media.

Comparison between ART Lab Solutions VitroMat and commercially available maturation medium on bovine embryo developmental competence.

Research was conducted by experienced bovine embryologists at the University of Adelaide, South Australia.

ART Lab Solutions base IVM media resulted in 10% greater blastocyst development over published commercially available media.  Data presented as mean ± SEM, n= 14 individual experiments, representative of 567-577 cumulus-oocyte complexes per treatment group. Embryos were assessed and results were recorded on embryonic day 8 post insemination, blastocysts were graded accordingly. Both groups used VitroFert, VitroWash, VitroCleave and VitroBlast for the remainder of the culture period.  All media were supplemented with 4mg/ml bovine serum albumin, no further serum was used (fetal calf/bovine serum) .
